A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu. In a Article，once mentioned of 246047-72-3, name: (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium

The synthesis of trigonal bipyramidal, square planar, and octahedral bis(phosphine) complexes of the formula trans-LyM(P((CH2)nCH{double bond, long}CH2)3)2, and their conversion to gyroscope-like molecules trans-Ly{A figure is presented} via three-fold intramolecular alkene metathesis/hydrogenation sequences, is reviewed. New data involving bis(phosphite) complexes are then described. Reactions of P(NMe2)3 and HO(CH2)nCH{double bond, long}CH2 (n = a, 3; b, 4; c, 5; d, 6; e, 8; f, 9) afford the ligands P(O(CH2)nCH{double bond, long}CH2)3 (26a-f, 79-96%). Reactions of 26a,b,e,f and Fe(BDA)(CO)3 (BDA = benzylideneacetone) give trans-Fe(CO)3(P(O(CH2)nCH{double bond, long}CH2)3)2 (27a,b,e,f) as yellow or green oils in 17-64% yields after workup. Two representative complexes (27b,e) are treated with Grubbs’ catalyst (2 × 6.5 mol%). NMR analyses of the resulting crude trans-Fe(CO)3(P(O(CH2)nCH{double bond, long}CH(CH2)nO)3P) (28b,e) suggest mixtures of Z/E isomers and perhaps oligomers. Subsequent ClRh(PPh3)3-catalyzed hydrogenations afford the title molecules trans{A figure is presented} (29b,e) as oils of 82-83% purity by 31P NMR. Although various properties of 29b,e can be compared to 27b,c, they could not be induced to solidify or crystallize, hampering purification.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.name: (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium.

As a guide for selective reactions toward either Z- or E-alkene in a metathesis reaction, the relative preference of metathesis Ru catalysts for each stereoisomer was determined by a method using time-dependent fluorescence quenching. We found that Ru-1 prefers the Z-isomer over the E-isomer, whereas Ru-2 prefers the E-isomer over the Z-isomer. The Z/E-alkene preference of the catalysts precisely predicted the Z/E isomeric selectivity in the metathesis reactions of diene substrates possessing combinations of Z/E-alkenes. For the diene substrates, the rate order of the reactions using Ru-1 was Z,Z-1,6-diene > Z,E-1,6-diene > E,E-1,6-diene, while the completely opposite order of E,E-1,6-diene > Z,E-1,6-diene > Z,Z-1,6-diene was exhibited in the case of Ru-2.

We report an asymmetric, catalytic transannular aldolization that provides polycyclic products useful for natural product synthesis. We found that a proline-derivative catalyzes the transannular aldol reaction of 1,4-cyclooctanediones to the corresponding cyclic beta-hydroxy ketones in good yields and with high enantioselectivities. The utility of our reaction has been demonstrated in a total synthesis of (+)-hirustene. Copyright

(Chemical Equation Presented) Jack of all trades? A ruthenium(IV) carbene complex catalyzes the diastereoselective direct arylation of alkenes using aryl chlorides with high efficiency, which sets the stage for the development of a direct arylation-hydrosilylation sequence (see scheme).

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 246047-72-3 is helpful to your research., Computed Properties of C46H65Cl2N2PRu

Several cationic alkoxy(alkyl)carbene complexes containing the Ru(L)(PPh3))eta-C5H5) (L=CO or PPh3) moiety have been deprotonated with NaOMe to the corresponding vinyl ether derivatives.The reaction is reversed by addition of PF6.Many of the vinyl ether complexes were obtained as mixtures of E and Z isomers; the X-ray structure of Ru(C(OPri)=CHPh)(CO)(eta-C5H5) shows that it is obtained only as the E isomer, and that unit cell contains equal numbers of the two enantiomers.Ru(C(OPri)=CHPh)(CO)(PPh3)(eta-C5H5) is monoclinic, space group P21/c, with 10.337(5), b 15.161(4), c 18.714(5) Angstroem, beta 90.83(3) deg, and Z=4; 2240 reflections 2.5?*I(> were refined to R=0.0388, Rw=0.0436.Important distances: Ru-C(vinyl) 2.103(6), Ru-CO 1.832(7), Ru-P 2.298(2), C=C(vinyl) 1.335(8), C-OMe 1.381(7) Angstroem.Addition of NaOMe to the product of the reaction between RuCl(PPh3)2(eta-C5H5) and HC<*>CC(O)Me in MeOH afforded a mixture of Ru(C<*>CC(O)Me)(PPh3)2(eta-C5H5) and Ru(C(OMe)=CHC(O)Me)*PPh3)2(eta-C5H5).The latter losses PPh3 on standing in solution ar ambient temepratures, forming the chelate complex cyclo-Ru(C(OMe)=CHC(O)Me(PPh3)(eta-C5H5).The similar conversion of Ru(C(OMe)=CHC(O)Me)(PPh3)2(eta-C5H5) to the corresponding chelate complex required heating at 65 def C for 75 minutes.
