The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a Article，once mentioned of 12150-46-8, Computed Properties of C34H28FeP2
Reactions of the platinum complexes cis-[PtCl2(PPh 3)2], [PtCl2(dppf)], or [PtCl 2(dppe)], and the palladium complexes, [PdCl2(PPh 3)2] or [PdCl2(dppe)], with bis(cyanomethyl)sulfone NCCH2SO2CH2CN in methanol with added trimethylamine base gave the new cyano-substituted metallathietane-3,3-dioxide complexes [M{CH(CN)SO2CH(CN)}L 2] (M = Pd, Pt) in good yields and purities. 1H and 31P{1H} NMR spectroscopy indicates that (in the majority of cases) the products are formed as a mixture of cis and trans isomers, with regard to the disposition of the cyano groups across the four-membered ring. An X-ray structure determination on a crystal of [Pd{CH(CN)SO2CH(CN)} (PPh3)2] showed it to be of the cis isomer, the first structurally characterized cis isomer of this type of complex. The four-membered palladacyclic ring is highly planar, in contrast to other metallathietane-3,3- dioxide complexes that have puckered rings. Factors influencing the relative abundances of the two isomers of [Pd{CH(CN)SO2CH(CN)}(PR 3)2] have been investigated by means of NMR spectroscopy and DFT calculations.
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 12150-46-8 is helpful to your research., Computed Properties of C34H28FeP2
