A document type is Article, introducing its new discovery.

Five new complexes [RuCl2(SIMes)(Ind)(O-pXC5H4)] bearing different para-substituted triphenylphosphites (X = H, OCH3, CF3, Cl, SF5 and CN) were synthesised and used to study the effect of the electronic properties of the phosphite on olefin metathesis activity. Investigations of the physical properties of the new ligands and complexes were performed using physicochemical and DFT calculations. The catalytic activity of the complexes was benchmarked in challenging ring closing metathesis transformations featuring the formation of tetra-substituted double bonds. Complex [RuCl2(SIMes)(Ind)P(O-pCF3C5H4)3] (3c) exhibited a particularly high catalytic activity, superior to state-of-the-art catalysts, and was further tested on a wide range of substrates.

Ru-catalyzed olefin metathesis has been successfully applied to the synthesis of biscardanol derivatives and cardanol-based porphyrins. Using Hoveyda-Grubbs catalyst (C627), the reactions were performed with various cardanol derivatives (2, 5, 7, and 9) to make novel biscardanol derivatives. With the use of the second-generation Grubbs catalyst (C848) and Ti(OiPr)4, the ring-closing metathesis of cardanol-based porphyrin 11 was carried out to afford cyclic cardanol-based porphyrin derivative 12.

In the presence of conventional supported hydrotreating catalysts, substituted benzenes undergo two parallel initial reactions, i.e., hydrogenolysis of carbon sp2-heteroatom bonds and hydrogenation of the aromatic ring. It has been reported that they are suitable model compounds for evaluating the hydrogenolysis vs. hydrogenation activity of these catalysts. Hydroprocessing of substituted benzenes, e.g., aniline, phenol, diphenylsulfide, and chlorobenzene, was conducted in a batch reactor at 280C and 70 bar H2 pressure over unsupported transition metal sulfides, i.e. Co, Ni, Nb, Mo, Ru, Rh, Pd, and W sulfides. Chlorobenzene and diphenylsulfide mainly reacted via initial hydrogenolysis of the carbon-substituent bond, while aniline and phenol reacted via initial hydrogenation of the aromatic ring. The results confirmed the influence of mesomeric effects on the reactivity of organic models toward sulfided catalysts. Quantum chemical calculations indicated that the hydrogenolysis constants correlated with the pi-electron density on the carbon bearing the substituent and with the overall calculated pi-electron transfer between the substituents and the benzene ring. It was assumed that hydrogenolysis of carbon sp2-substituent bonds resulted from the attack by a soft nucleophilic species like a hydride ion on the carbon bearing the substituent.

The synthesis and characterization of latent 18-electron ruthenium benzylidene complexes (PCy3)((kappaN,O)-picolinate)2RuCHPh (5) and (H2IMes)((kappaN,O)-picolinate)2RuCHPh (6) are described. Both complexes appear as two isomers. The ratio between the isomers is dependent on l-type ligand. The complexes are inactive in ring-closing metathesis and ring-opening metathesis polymerization reactions even at elevated temperatures in the absence of stimuli. Upon addition of HCl, complexes 5 and 6 become highly active in olefin metathesis reactions. The advantage of the latent catalysts is demonstrated in the ring-opening metathesis polymerization of dicyclopentadiene, where the latency of 6 assures adequate mixing of catalyst and monomer before initiation. Trapping experiments suggests that the acid converts the 18-electron complexes into their corresponding highly olefin metathesis active 14-electron benzylidenes.

In a Article，once mentioned of 14564-35-3, Safety of Dichlorodicarbonylbis(triphenylphosphine)ruthenium(II)

The hydrogenation of myrcene catalyzed by Ru, Cr, Ir and Rh complexes leads to the formation of a complex mixture of mono-, di- and trihydrogenated products. Seven major products have been characterized, showing that they arise from the sigma-alkyl and/or eta3-allyl intermediates formed by the reaction of metal catalysts with both terminal CC bonds of myrcene. A good control of chemoselectivity has been achieved through the appropriate choice of the metal and reaction conditions. Monohydrogenated products have been obtained with excellent combined selectivity of 95-98% at a high conversion of myrcene (>80%). Among the catalysts studied, rhodium complexes show the highest activity and selectivity, especially at temperatures lower than 100 C.

The synthesis of a ruthenium complex containing an N-heterocylic carbene (NHC) and a mesoionic carbene (MIC) is described wherein addition of a Br°nsted acid results in protonolysis of the Ru-MIC bond to generate an extremely active metathesis catalyst. Mechanistic studies implicated a rate-determining protonation step in the generation of the metathesis-active species. The activity of the NHC/MIC catalyst was found to exceed those of current commercial ruthenium catalysts.
