Safety of Tris(triphenylphosphine)chlororhodium. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Tris(triphenylphosphine)chlororhodium, is researched, Molecular C54H45ClP3Rh, CAS is 14694-95-2, about Isomerising hydrosilylation of oleic acid esters with industrially important triethoxysilanes. Author is Herzog, Rainer F.; Huber, Thimo; Riepl, Herbert M..
It is a desirable reaction to shift the double bond of the naturally abundant oleic acid from plant oils to the terminal position to enable suitable hydrosilylation or other hydrometallations to obtain intermediates of polymer manufacture The catalyst [Ir(OMe)(1,5-cod)]2 is able to catalyze the 8-fold isomerization using simple alkyl silanes as reactant, but tech. more interesting alkoxysilanes do not react. It was found that combined application of HCo(N2)(PPh3)3 and Wilkinson’s catalyst isomerize and hydrosilylate oleic acid to the desired ω-triethoxysilyloctadecanoic acid ethylester but with still poor yield. Considerable improvement was found when the phosphines are changed, i.e. tris-p-tolylphosphine being the most effective yielding nearly 50% terminally hydrosilylated oleic acid ester.
As far as I know, this compound(14694-95-2)Safety of Tris(triphenylphosphine)chlororhodium can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
