Syntheses, spectral and structural characterization of eta5- and eta6-cyclic pi-perimeter hydrocarbon platinum group metal complexes containing pyridazine-NHC analogues

A family of platinum group metal complexes containing bidentate pyridazine-NHC ligands (L1 = 3,6-bis(N-n-methylimidazolyl)pyridazine dichloride, L2 = 3,6-bis(N-n-butylimidazolyl)pyridazine dichloride) have been synthesized. The typical mechanism of the reactions for these syntheses involved an in situ carbene transfer reactions. Reaction of L1/L2 with silver oxide in absence of light yielded silver-NHC complexes (1) and (2). When, the respective metal precursors were added to the silver-NHC complexes, transmetallation occurred with the possible isolation of the following cationic complexes: [(eta6-C6H6)Ru(L)Cl]2+ {L = L1 (3), L2 (5)}, [(eta6-p-iPrC6H 4Me)Ru(L)Cl]2+ {L = L1 (4), L2 (6)}, [Cp *Rh(L)Cl]2+ {L = L1 (7), L2 (9)} and [Cp *Ir(L)Cl]2+ {L = L1 (8), L2 (10)}. All these complexes were stable in ambient atmosphere, and could be obtained in good yield. All these complexes were characterized by spectroscopic analyses. The molecular structure of the complex 9 was determined by single crystal X-ray diffraction studies.

Ruthenium(II)-polypyridyl zirconium(IV) metal-organic frameworks as a new class of sensitized solar cells

A series of Ru(ii)L2L? (L = 2,2?-bipyridyl, L? = 2,2?-bipyridine-5,5?-dicarboxylic acid), RuDCBPY, -containing zirconium(iv) coordination polymer thin films have been prepared as sensitizing materials for solar cell applications. These metal-organic framework (MOF) sensitized solar cells, MOFSCs, each are shown to generate photocurrent in response to simulated 1 sun illumination. Emission lifetime measurements indicate the excited state quenching of RuDCBPY at the MOF-TiO2 interface is extremely efficient (>90%), presumably due to electron injection into TiO2. A mechanism is proposed in which RuDCBPY-centers photo-excited within the MOF-bulk undergo isotropic energy migration up to 25 nm from the point of origin. This work represents the first example in which a MOFSC is directly compared to the constituent dye adsorbed on TiO2 (DSC). Importantly, the MOFSCs outperformed their RuDCBPY-TiO2 DSC counterpart under the conditions used here and, thus, are solidified as promising solar cell platforms.

Total syntheses of ipomoeassin B and E

A concise, flexible, and efficient total synthesis of the cytotoxic resin glycosides ipomoeassin B (1) and ipomoeassin E (2) is reported which features the advantages of a novel protecting group strategy employing (Z)-3-dimethyl(phenyl)silyl-2-propenoic acid as cinnamic acid surrogate. The use of this readily available compound allowed the macrocycle of the glycolipids to be formed by ring closing olefin metathesis (RCM) with the aid of the second generation Grubbs carbene complex 12. The resulting E/Z mixture could be selectively hydrogenated using Wilkinson’s catalyst [RhCl(PPh3)3] without affecting the unsaturated esters in the periphery of the compound, before the C-silyl group was cleaved off with TASF [tris(dimethylamino)sulfonium difluorotrimethylsilicate] under notably mild conditions to release the required cinnamate moiety. Other key steps of the synthesis route comprise the formation of the disaccharide linkage by the trichloroacetimidate method, the formation of the chiral acid segment 19 via a VO(acac)2-catalyzed, tert-BuOOH-induced oxidative rearrangement of the optically pure furyl alcohol (-)-15 (Achmatowicz-type reaction), and a reductive cleavage of the 4,6-O-p-methoxybenzylidene acetal in 5 with NaBH3CN and Me3SiCl (TMSCl), the regiochemical course of which was found to be opposite to that previously reported in the literature for sterically less encumbered substrates.

Total Synthesis of (-)-Lasonolide A

The lasonolides are novel polyketides that have displayed remarkable biological activity in vitro against a variety of cancer cell lines. Herein we describe our first-generation approach to the formal synthesis of lasonolide A. The key findings from these studies ultimately allowed us to go on and complete a total synthesis of lasonolide A. The convergent approach unites two highly complex fragments utilizing a Ru-catalyzed alkene-alkyne coupling. This type of coupling typically generates branched products; however, through a detailed investigation, we are now able to demonstrate that subtle structural changes to the substrates can alter the selectivity to favor the formation of the linear product. The synthesis of the fragments features a number of atom-economical transformations which are highlighted by the discovery of an engineered enzyme to perform a dynamic kinetic reduction of a beta-ketoester to establish the absolute stereochemistry of the southern tetrahydropyran ring with high levels of enantioselectivity.

METHODS OF MAKING ORGANIC COMPOUNDS BY METATHESIS

Described are methods of making organic compounds by metathesis chemistry. The methods of the invention are particularly useful for making industrially-important organic compounds beginning with starting compositions derived from renewable feedstocks, such as natural oils. The methods make use of a cross-metathesis step with an olefin compound to produce functionalized alkene intermediates having a pre-determined double bond position. Once isolated, the functionalized alkene intermediate can be self-metathesized or cross-metathesized (e.g., with a second functionalized alkene) to produce the desired organic compound or a precursor thereto. The method may be used to make bifunctional organic compounds, such as diacids, diesters, dicarboxylate salts, acid/esters, acid/amines, acid/alcohols, acid/aldehydes, acid/ketones, acid/halides, acid/nitriles, ester/amines, ester/alcohols, ester/aldehydes, ester/ketones, ester/halides, ester/nitriles, and the like.

Bis(allyl)-ruthenium(IV) complexes as highly efficient catalysts for the redox isomerization of allylic alcohols into carbonyl compounds in organic and aqueous media: Scope, limitations, and theoretical analysis of the mechanism

The catalytic activity of the bis(allyl)-ruthenium(IV) dimer [{Ru(eta3:eta3-C10H16)(mu-Cl) Cl}2] (C10H16 = 2,7-dimethylocta-2,6-diene-1,8- diyl) (1), and that of its mononuclear derivatives [Ru(eta3: eta3-C10H16)Cl2(L)] (L = CO, PR3, CNR, NCR) (2) and [Ru(eta3:eta3-C 10H16)Cl(NCMe)2][SbF6] (3), in the redox isomerization of allylic alcohols into carbonyl compounds, both in tetrahydrofuran and in water, is reported. In particular, a variety of allylic alcohols have been quantitatively isomerized using [{Ru(eta3: eta3-C10H16)(mu-Cl)Cl}2] (1) as catalyst, the reactions proceeding in all cases faster in water. Remarkably, complex 1 has been found to be the most efficient catalyst reported to date for this particular transformation, leading to TOF and TON values up to 62 500 h-1 and 1 500 000, respectively. Moreover, catalyst 1 can be recycled and is capable of performing allylic alcohol isomerizations even in the presence of conjugated dienes, which are known to be strong poisons in isomerization catalysis. On the basis of both experimental data and theoretical calculations (DFT), a complete catalytic cycle for the isomerization of 2-propen-1-ol into propenal is described. The potential energy surfaces of the cycle have been explored at the B3LYP/6-311+G(d,p)//B3LYP/6-31G(d,p) + LAN2DZ level. The proposed mechanism involves the coordination of the oxygen atom of the allylic alcohol to the metal. The DFT energy profile is consistent with the experimental observation that the reaction only proceeds under heating. Calculations predict the catalytic cycle to be strongly exergonic, in full agreement with the high yields experimentally observed.

Photonic wires of nanometric dimensions. Electronic energy transfer in rigid rodlike Ru(bpy)32+-(ph)n-Os(bpy)3 2+ compounds (ph = 1,4-phenylene; n = 3, 5, 7)

We have synthesized nine rodlike compounds of nanometric dimension with general formula [M(bpy)3-(ph)n-M?(bpy)3]4+ (M = M? = Ru(II); M = M? = Os(II); M = Ru(II), M? = Os(II); bpy = 2,2?-bipyridine; ph = 1,4-phenylene; n = 3, 5, 7; the central phenylene unit bears two alkyl chains for solubility reasons; the metal-to metal distance is 4.2 nm for the longest spacer). The absorption spectra and the luminescence properties (emission spectra, quantum yields, and excited-state lifetimes) of the nine dinuclear complexes have been investigated in acetonitrile solution at 293 K and in butyronitrile rigid matrix at 77 K. The results obtained have been compared with those found for the separated chromophoric units ([Ru(bpy)3]2+, [Os(bpy)3]2+, and oligophenylene derivatives). The absorption spectrum of each dinuclear complex is essentially equal to the sum of the spectra of the component species, showing that intercomponent electronic interactions are weak. In the homodinuclear compounds, the strong fluorescence of the oligophenylene spacers is completely quenched by energy transfer to the metal-based units, which exhibit their characteristic metal-to-ligand charge-transfer (MLCT) phosphorescence. In the heterodinuclear compounds, besides complete quenching of the fluorescence of the oligophenylene spacers, a quenching of the phosphorescence of the [Ru(bpy)3]2+ chromophoric unit and a parallel sensitization of the phosphorescence of the [Os(bpy)3]2+ chromophoric unit are observed, indicating the occurrence of electronic energy transfer. The rate of the energy-transfer process from the [Ru(bpy)3]2+ to the [Os(bpy)3]2+ unit is practically temperature independent and decreases with increasing length of the oligophenylene spacer (in acetonitrile solution at 293 K, ken = 6.7 ¡Á 108 s-1 for n = 3; ken = 1-0 ¡Á 107 s-1 for n = 5; ken = 1-3 ¡Á 106 s-1 for n = 7). It is shown that such an energy-transfer process takes place via a Dexter-type mechanism (superexchange interaction) with an attenuation coefficient of 0.32 per A and 1.5 per interposed phenylene unit.

Metal-assisted preparation of the alkenyl ketone and carbonyl complexes from 1-alkyne and H2O: C-C triple bond cleavage of terminal alkyne

Reactions of Cp*RhCl2(PPh3) (1) with 1-alkyne and H2O in the presence of KPF6 generated alkenyl ketone complexes [Cp*Rh(CRCHCOCH2R)(PPh3)](PF6) (2) (R = Ph (a), C6H4-p-Me (b), C6H 4-p-COOMe (c), C6H4-p-NO2 (d)). A similar complex [Cp*Rh(CPhCHCOCH2Ph)(PMePh2)] (PF6) (2e) was obtained by use of Cp*RhCl 2(PMePh2). It was revealed by X-ray analyses of 2b, 2c and 2e that the complexes 2 consist of the five-membered ring structures bound by the carbon and oxygen atoms of the alkenyl ketone group. Similar reactions of Cp*IrCl2(PPh3) (6) or (C6Me 6)RuCl2(PPh3) (7) proceeded with a cleavage of C-C triple bond of 1-alkyne without formation of an alkenyl ketone complex, affording the corresponding carbonyl complexes, [Cp*IrCl(PPh 3)(CO)](PF6) (8) or [(C6Me6) RuCl(PPh3)(CO)](PF6) (9). The diphosphine complexes [(Cp*MCl2)2{mu-diphos}] (4: M = Rh, diphos = dppm,; 12a: M = Ir, diphos = dppm; 12b: M = Ir, diphos = dppb) gave a Cl-bridged rhodium complex [{Cp*Rh(mu-Cl)}2{mu-dppm}](PF 6)2 (5), mono-carbonyl or dicarbonyl iridium complexes,[(Cp*IrCl2){mu-dppm}{Cp*IrCl(CO)}](PF 6)(13a) or [{Cp*IrCl(CO)}2{mu-dppb}](PF 6)2 (14b), respectively.
