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, SDS of cas: 12150-46-8
Preparation of a series of NiL(eta2-C 60) complexes (L = 1,2-bis(diphenylphosphino)ethane, and 1,1?-bis(diphenylphosphino) ferrocene) by zinc dust reduction
A simple method for preparation of nickel-fullerene coordination complexes has been developed. NiLCl2(Br2) and C60 mixtures are reduced by zinc dust upon heating in o-dichlorobenzene. Diffusion of hexane into the reaction mixture results in formation of crystals of NiL(eta2-C60)ssolvent (L = 1,2-bis(diphenylphosphino)ethane (dppe, 1), 1,3-bis(diphenylphosphino)propane (dppp, 2) and 1,1?-bis(diphenylphosphino)ferrocene (dppf, 3)). Nickel coordinates to the 6-6 bonds of C60 by eta2- type and has distorted square-planar geometry. The average Ni-C(C60) bond lengths are 1.936(6)-1.977(3) A. We found that increase in the P(L)-Ni-P(L) angle and the dihedral angle between the PNiP and CNiC planes results in elongation of the Ni-C(C60) and Ni-P(L) bonds by 0.04-0.06 A. Complexes 1-3 contain zero-valent nickel since fullerenes are neutral according to the IR- and visible-NIR spectra. Some of the IR-active bands of C60 are split into three bands in spectra of 1-3 due to C60 symmetry lowering, and the F1u(4) C60 mode is shifted to lower wave numbers due to the pi-back donation. The formation of 1-3 is accompanied by appearance of new bands in the visible range at 435-447 and 661-680 nm. 2013
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., SDS of cas: 12150-46-8
