Polynuclear complexes of Ru(ll) based on the octadentate ligand 5,5′-bis(2-pyridyl)-3,3′-bi(1,2,4-triazole) (BPBT): Synthesis, spectroscopic and photophysical properties

The synthesis and characterization of the redox and excited state properties of three complexes (Ru(bpy)2(bpbtH2)2+, [Ru(bpy)2]2(bpbtH2)4t and [Ru(bpy)2]3(bpbt)4+) derived from the title ligand “bpbt” are reported. The coordination of the Ru(bpy)2 unit is believed to occur via N1 of the triazole and the pyridine nitrogen in the mononuclear and binuclear complexes. In the trinuclear complex the third unit is linked via N1 and N4′ of the bis(triazole) part of the ligand. Electrochemical studies of the mono-, bi- and trinuclear complexes show one, two and three one-electron oxidations(s) of the Ru-center(s). On the reduction side, up to -2.0 V only reduction of the spectator ligands bpy can be observed, each as two waves involving one, two and three electrons in the mono-, bi- and trinuclear complexes, respectively. FAB mass spectral data and fragmentation patterns of the binuclear complex are discussed. Mixed-valence forms of the bi- and trinuclear complexes can be prepared by chemical oxidation and these show strong absorption in the infra-red region corresponding to intervalence (IT) transitions. Analysis of the IT bands shows that the extent of electron delocalization is quite high in both cases, suggesting a fairly strong metal-metal interaction. The lowest excited state in all cases involves charge transfer from Ru(ll) to the bipyridine ligands, Ru(ll)->bpy. All three complexes show emission in solution at ambient temperature. The absorption and emission properties are sensitive to solution pH. Laser flash photolysis studies show a strong intensity dependence for the luminescence and transient absorptions and this is attributed to excited state annihilation processes, possibly via electron transfer.

Ruthenium-catalyzed oxidative homocoupling of arylboronic acids in water: Ligand tuned reactivity and mechanistic study

Molecular catalysts based on water-soluble arene-Ru(II) complexes ([Ru]-1-[Ru]-5) containing aniline (L1), 2-methylaniline (L2), 2,6-dimethylaniline (L3), 4-methylaniline (L4), and 4-chloroaniline (L5) were designed for the homocoupling of arylboronic acids in water. These complexes were fully characterized by 1H, 13C NMR, mass spectrometry, and elemental analyses. Structural geometry for two of the representative arene-Ru(II) complexes [Ru]-3 and [Ru]-4 was established by single-crystal X-ray diffraction studies. Our studies showed that the selectivity toward biaryls products is influenced by the position and the electronic behavior of various substituents of aniline ligand coordinated to ruthenium. Extensive investigations using 1H NMR, 19F NMR, and mass spectral studies provided insights into the mechanistic pathway of homocoupling of arylboronic acids, where the identification of important organometallic intermediates, such as sigma-aryl/di(sigma-aryl) coordinated arene-Ru(II) species, suggested that the reaction proceeds through the formation of crucial di(sigma-aryl)-Ru intermediates by the interaction of arylboronic acid with Ru-catalyst to yield biaryl products.

Total synthesis of platencin

(Chemical Equation Presented) The asymmetric total synthesis of the newly discovered and potent antibiotic platencin has been achieved. The approach makes use of an asymmetric Diels-Alder reaction, a gold(I)-catalyzed cyclization, and a homoallyl radical rearrangement to forge the polycyclic architecture of this intriguing target (see scheme, SEM=2-(trimethylsilyl)ethoxymethyl).

Reactions of the cationic fragments [RuCp(PPh2NHR) 2]+ and [RuTp(PPh2NHR)2]+ (R = Ph, re-Pr) with Alkynes: Formation of four-membered azaphosphacarbenes

The synthesis of RuCp(PPh2NHR)2Cl (1a,b; R = Ph, n-Pr) and RuTp(PPh2NHR)2Cl (2a,b) is reported. Chloride abstraction from 1a with AgCF3SO3 affords RuCp(PPh 2NHPh)2(eta1-OSO2CF3) (3), whereas when AgSbF6 is used instead [RuCp(kappa2(P, P)-PPh2NHC6H4PPh2)(NH 2-Ph)]+ (4) is formed. In the course of this reaction the P-N bond of one PPh2NHPh ligand is cleaved while a new P-C bond is formed, with concomitant formation of an aniline ligand. In the presence of Ag+ (CF3SO3- or SbF6 -) complexes 1 and 2 react with terminal alkynes HC?CR? (R? = Ph,p-C6H4Me, n-Bu) and propargylic alcohols to give novel azaphosphacarbene complexes of the types [RuCp(kappa 2(C,P)=C(CH2R?)N(R)PPh2) (kappa1(P)-PPh2NHR)]+ (5a-c, 6a-c), [RuTp(kappa2(C,P)=C(CH2R?)N(R)PPh 2)(kappa1(P)-PPh2NHR)]+ (14a,b, 15a-c), [RuCp(kappa2(C,P)= C(CH=CPh2)N(Pr n)PPh2)(kappa1(P)-PPh2NHPr n)]+ (12), and [RuTp(kappa2(C,P)=C(CH=CPh 2)N(Prn)-PPh2)(kappa1(P)-PPh 2NHPrn)]+ (17). These reactions proceed via vinylidene and allenylidene intermediates, respectively, which could be isolated in some cases: viz. [CpRu(PPh2NHPh)2-(=C=C=CPh 2)]+ (11) and [RuTp(PPh2NHR) 2(=C=C=CPh2)]+ (16a,b). Furthermore, complexes 1a,b react with 3-butyn-1-ol to yield the oxacyclopentylidene complexes [CpRu(PPh2-NHR)2(=C4H6O)] + (7a,b). In sharp contrast to 6a-c (R = n-Bu), 5a-c (R = Ph) turned out to be quite sensitive toward traces of water, leading eventually to the formation of the aminocarbene complexes [RuCp(=C(CH2R)NHPh)(PPh 2NHPh)(kappa1(P)-PPh2OH)]+ (8a,b) featuring a kappa1(P)-coordinated PPh2OH ligand. This ligand could be easily deprotonated to yield the neutral complex RuCp(=C(CH 2Ph)NHR)(PPh2NHPh)(kappa1(P)-OPPh 2) (10a,b). The formation of these complexes is reversible. Finally, representative structures have been determined by X-ray crystallography.

Factors relevant for the regioselective cyclopolymerization of 1,6-heptadiynes, N,N-dipropargylamines, N,N-dipropargylammonium salts, and dipropargyl ethers by RuIV-alkylidene-based metathesis initiators

The factors relevant for the regioselectivity of insertion of various 1,6-heptadiynes, N,N- dipropargylamines, N,N-dipropargylammonium salts anddipropargyl ethers into different RuIV-alkylidenes, i.e., [R u(CF 3COO)2(IMesH2)(=CHR), (R = 2,4,5-(MeO) 3-C6H2(l1) 2-(2-PrO)-5-NO2-C 6H3 (I3), 2-(2- PrO)-C6H4 (I4)), [Ru(CF3COO)2(1,3-dimesityl-3,4,5,6-tetrahydropyrimidin-2- ylidene)(=CH-2-(2-PrO)-5- NO2-C6H3)] (I2), [Ru(CF3COO)2(3-mesityl-1-((1?fl)-1?- phenylethyl)-imidazolin-2-ylidene)(=CH-2-(2-PrO)- C6H4)] (I5) and [Ru(C6F5COO)2(IMesH 2)(=CH-2-(2-PrO)-C6H4)] (I6), (IMesH 2 = 1,3-dimesitylimidazolin-2- ylidene), is described. 13C NMR experiments revealed that all polymers synthesized by the action of I1-I6 consisted virtually solely (>95percent) of five-membered repeat units, i.e., (cyclopent-1-enylene)-1,2-vinylenes, 3,4-(1 H-2,5-dihydropyrrylenium)-3,4- vinylenes, and (2-pentyl-2,5-dihydrofurylene)-3,4-vinylenes, respectively. The 13C NMR-based assignments were supported by the synthesis of model compounds, i.e., (cyclopent- 3-ene-1,1-diyldimethylbis(tris(3,5-dimethoxyphenyl) carboxylate) (MC1) and N-propyl-N-ethyl-2,5-dihydro- pyrrolium tetrafluoroborate (MC2), as well as by ene-yne cross metathesis reactions of 3-(propargyloxy)- 1-octyne (M6) with trimethylallylsilane. In the polymerization of N-ethyl-N,N-dipropargylamine (M9), an intermediate was isolated that shedslight onto the role of heteroatoms in the 4-position of 1,6-heptadiynes in cyclopolymerization. In addition, in the cyclopolymerization of M9 b y I4 the product resulting from backbiting has been isolated and explains for the low polymerization propensity of Ru-alkylidenes for N-alkyl-N,N-dipropargylamines.

Isothiourea-catalysed chemo- and enantioselective [2,3]-sigmatropic rearrangements of N,N-diallyl allylic ammonium ylides

The isothiourea-catalysed chemo- and enantioselective [2,3]-sigmatropic rearrangement of N,N-diallyl allylic ammonium ylides is explored as a key part of a route to free functionalised alpha-amino esters and piperidines. The [2,3]-sigmatropic rearrangement proceeds with excellent diastereo- and enantiocontrol (>95:5 dr, up to 97% ee), with the resultant N,N-diallyl alpha-amino esters undergoing either mono- or bis-N-allyl deprotection. Bis-N-allyl deprotection leads to free alpha-amino esters, while the mono-deprotection strategy has been utilized in the synthesis of a target functionalised piperidine.
