Ruthenium trisbipyridine C60 dyads linked via para-phenyleneethynylene units have been prepared. They displayed a rapid energy transfer from Ru to C60 with a rate that was independent of distance, from 1.1 to 2.3 nm. The results are explained by a hopping mechanism involving a bridge-localized excited-state. In fact, for the longest bridge this state was lower in energy than the Ru-based MLCT state, as evidenced by the spectroscopic data.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C20H16Cl2N4Ru, you can also check out more blogs about15746-57-3

The scope of ruthenium (Ru)-catalyzed cross metathesis (CM) of allyl-decorated polyhedral oligomeric silsesquioxanes (POSS) was explored. A variety of different commercial and non-commercial ruthenium complexes were tested to determine that the nitro-activated Ru catalyst is optimal for this transformation. The reported transformation was used to prepare selected hybrid steroid-POSS compounds.

RNA editing by adenosine deamination is a form of epigenetic control of gene expression wherein the ADAR enzymes convert adenosine to inosine in RNA often changing the meaning of codons. The pre-mRNA for the 2c subtype of serotonin receptor (5-HT2cR) is shown here to support small molecule binding near known editing sites. Furthermore, a helix-threading peptide binds this site and inhibits the in vitro reaction of ADAR2 in an RNA-substrate selective manner. This is the first example of substrate-selective inhibition of editing by an RNA-binding small molecule and sets the stage for the development of new reagents capable of controlling gene function through manipulation of mRNA editing.

Basicities of the cyanide ligands in a series of Cp?M(L)2CN complexes were investigated by measuring their heats of protonation (-deltaHCNH) by CF3SO3H in 1.2-dichloroethane solution at 25.0 C to give Cp?M(L)2(CNH)+CF3SO3 -, in which the N-H+ group is probably hydrogen-bonded to the CF3SO3- anion. Basicities (-deltaHCNH) of the CpRu(PR3)2CN complexes increase from 20.5 (PPh3) to 22.4 (PMe3) kcal/mol with increasing donor abilities of the phosphine ligands. Basicities of all the Cp?Ru(PR3)2CN complexes, where Cp? = Cp or Cp*, are linearly correlated with their vCN values; the nonphosphine complexes. CpRu(l.10-phen)CN and CpRu(COD)CN, do not follow the same correlation. For a large number of Cp?M(L)2CN complexes (M = Ru, Fe, L2 = mono- and bidentate phosphines, CO, 1,10-phen, and COD), their vCN values parallel vCN values of their protonated Cp?M(L)2(CNH)+ analogues. Also, 31P NMR chemical shifts of the unprotonated Cp?M(PR3)2-CN and protonated CpM(PR3)2(CNH)+ complexes are linearly related. Despite the high basicity of Ru in Cp*Ru-(PMe3)2Cl (30.2 kcal/mol), the CN- in Cp*Ru(PMe3)2CN (25.0 kcal/mol) is the site of protonation: factors that determine whether protonation occurs at the Ru or the CN- are discussed.

The synthesis of water-soluble (eta6-arene)ruthenium(II) complexes based on pyrazolyl-naphthyridine ligands modified with a carboxylate group is reported. The complexes are easily accessible in good yields via complexation of [(arene)RuCl2]2 with 7-pyrazolyl-1,8- naphthyridine-2-carboxylic acid (1). All complexes have been characterized by spectroscopic and elemental analyses. The complexes {[Ru(eta6- arene)(N,N?-1)Cl]Cl} (arene = benzene (5), p-cymene (6)) were further confirmed by X-ray diffraction studies. These complexes are soluble in water (ca. 10 mg/mL) and are catalytically active in hydrogen-transfer reduction of carbonyl compounds in aqueous medium with the use of HCOOH/HCOONa as the hydrogen source.

(Chemical Equation Presented) Correct orientation: Macrocyclic paracyclophanes of multiple ring sizes and diverse functionality are prepared byolefin metathesis (see scheme for an example), through the exploitation of solution-phase quadrupolar interactions between the core arene and pendant pentafluoroarene units. This approach reverses the tendency for dimeric products to be formed during macrocyclizations.

The synthesis of new ruthenium-based catalysts applicable for both homogeneous and heterogeneous metathesis is described. Starting from the Hoveyda-Grubbs first generation (1) and the Hoveyda-Grubbs second generation (2) catalysts the homogeneous catalysts [RuCl((RO)3Si-C3H6-N(R?)-CO-C3F6-COO)({double bond, long}CH-o-O-iPr-C6H4)(SIMes)] (4: R = Et, R? = H; 5: R = R? = Me) (SIMes = 1,3-bis(2,4,6-trimethylphenyl)-4,5-dihydroimidazol-2-ylidene) were prepared by substitution of one chloride ligand with trialkoxysilyl functionalized silver carboxylates (RO)3Si-C3H6-N(R?)-CO-C3F6-COOAg (3a: R = Et, R? = H; 3b: R = R? = Me). These homogeneous ruthenium-species are among a few known examples with mixed anionic ligands. Exchange of both chloride ligands afforded the catalysts [Ru((RO)3Si-C3H6-N(R?)-CO-C3F6-COO)({double bond, long}CH-o-O-iPr-C6H4)(SIMes)] (9: R = Et, R? = H; 11: R = R? = Me) and [Ru((RO)3Si-C3H6-N(R?)-CO-C3F6-COO)({double bond, long}CH-o-O-iPr-C6H4)(PCy3)] (8: R = Et, R? = H; 10: R = R? = Me). The reactivity of the new complexes was tested in homogeneous ring-closing metathesis (RCM) of N,N-diallyl-p-toluenesulfonamide and TONs of up to 5000 were achieved. Heterogeneous catalysts were obtained by reaction of 4, 5 and 8-11 with silica gel (SG-60). The resultant supported catalysts 4a, 5a, 8a-11a showed reduced activity compared to their homogenous analogues, but rival the activity of similar heterogeneous systems.

The catalytic addition reactions of ferrocenyl ketones with terminal olefins in the presence of Ru(H)2(CO)(PPh3)3 as catalyst have been studied. Benzoylferrocene reacts with triethoxyvinylsilane, styrene and vinylferrocene, respectively, to give 1:1 coupling products I-III in high yields. C-H bond cleavage takes place at the carbon atom of the benzene ring at the ortho position of the carbonyl group and C-C bond formation takes place at the terminal carbon atom of the olefins. 2-Furoylferrocene reacts with vinylferrocene to give a 1:1 coupling product IV and the C-H bond cleavage takes place at the carbon atom of the furan ring at the ortho position of the carbonyl group and the C-C bond formation takes place at the terminal carbon atom of vinylferrocene. The new products I-IV have been characterized by elemental analysis, 1H-NMR and MS. The X-ray crystal structure of IV has been determined.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: ruthenium-catalysts, you can also check out more blogs about10049-08-8
