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. 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru. In a Article£¬once mentioned of 32993-05-8, Formula: C41H35ClP2Ru
Ruthenium metallodendrimers based on nitrile-functionalized poly(alkylidene imine)s
The preparation of the first- and second-generation of nitrile- functionalized poly(alkylidene imine) dendrimers with the organometallic ruthenium complex [Ru(eta5-C5H5) (PPh 3)2Cl] peripherally attached is described. The reaction of N,N?-bis-(cyanomethyl)piperazine (1), N,N?-bis[N?,N?- bis(cyanoethyl)aminoethyl]piperazine (2), or N,N,N?,N?- tetrakis(cyanoethyl)ethylenediamine (3) with [Ru(eta5-C 5H5)(PPh3)2Cl] (4) in the presence of TlPF6 gives the new air-stable ruthenium metallodendrimers 5, 6, and 7, respectively. These stable metallodendrimers are easily prepared and represent a novel quantitative method to solidify and chromatographically purify the otherwise semi-liquid nitrile-functionalized poly(alkylidene imine) dendrimers. The compounds were fully characterized by IR and 1H, 13C, and 31P NMR spectroscopy, and mass spectrometry. These dendrimers represent the first example of the utilization of nitrile-functionalized poly(alkylidene imine)s as cores in the preparation of metallodendrimers. Wiley-VCH Verlag GmbH & Co.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Formula: C41H35ClP2Ru, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 32993-05-8, in my other articles.
