Synthesis of Poly-γ-(p-diphenylphosphinophenyl) propylsiloxane Palladium(Ⅱ) Complex and Its Catalytic Property for Carbonylation
Abstract:
A fume silica-bound poly-V-(p-diphenylphosphinophenyl)propylsiloxane palladium(Ⅱ) complex was synthesized from 4-bromo-4-allylbenzene via hydrosilylation with triethoxysilane in the presence of tetrakis(triphenylphosphine)platinum complex as catalyst, phosphatization with potassium diphenylphosphide, sequentially, followed by immobilization on fume silica and reaction with palladium chloride. The title complex exhibited good catalytic activity in Heck carbonylation of aryl halides with aniline or butyl alcohol and can be used repeatedly without serious loss of activity. A possible structure pattern of the polymeric palladium complex has been suggested.
