The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.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, SDS of cas: 246047-72-3
sp Carbon chains surronded by sp3 carbon double helix: wire-like Pt(CC)nPt moieties that are spanned by two alpha,omega-diphosphines that bear heteroatoms or alkyl substituents
Reactions of trans-(C6F5)L2PtCl (2, L = Ph2P(CH2)4O(CH2)2CHCH2; 6, L = Ph2P(CH2)2C(CH3)2(CH2)3CHCH2) and H(CC)2H (HNEt2, cat. CuI) give trans-(C6F5)L2Pt(CC)2H (3, 7; 86-97%). Oxidative homocouplings (O2, cat. CuCl/TMEDA, acetone) yield trans,trans-(C6F5)L2Pt(CC)4PtL2(C6F5) (4, 8; 75-86%). Reactions with Grubbs catalyst, followed by hydrogenation, give mainlytrans,trans-(C6F5)(Ph2P(CH2)4O(CH2)6O(CH2)4PPh2)Pt(CC)4Pt(Ph2P(CH2)4O(CH2)6O(CH2)4PPh2)(C6F5) (5), with termini-spanning diphosphines, and trans,trans-(C6F5)(Ph2P(CH2)2C(CH3)2(CH2)8C(CH3)2(CH2)2PPh2)Pt(CC)4Pt(Ph2P(CH2)2C(CH3)2(CH2)8C(CH3)2(CH2)2PPh2)(C6F5) (9), with trans-spanning diphosphines, respectively. Reactions of trans,trans-(C6F5)(p-tol3P)2Pt(CC)4Pt(Pp-tol3)2(C6F5) with Ph2P(CH2)2C(CH3)2(CH2)8C(CH3)2(CH2)2PPh2 and p-tol2P(CH2)3(CF2)8(CH2)3Pp-tol2 give 10 (70%, the isomer of 9 with termini-spanning diphosphines, and the analogous adduct of the fluorinated diphosphine. However, the latter oligomerizes upon attempted workup. The crystal structure of 5 shows that the sp3 chains adopt a chiral double-helical conformation about the sp chain, with the endgroups defining a 164.1¡ã angle. Additional conformational properties of the preceding complexes are analyzed in detail, and dynamic properties are probed by low temperature NMR experiments.
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., SDS of cas: 246047-72-3
