Synthesis of polysiloxane-supported ferrocenyl selenoether platinum complexes and their catalytic behavior in the hydrosilylation of olefins with triethoxysilane
摘要:
Polysiloxane-supported ferrocenyl selenoether platinum complex was prepared from 1,1'-bis(undecenylseleno)ferrocene via hydrosilylation with triethoxysilane, followed by immobilization on fumed silica and then reaction with potassium chloro-platinite. Fumed silica-bound (undecenylseleno)- or 1,1'-bis(undecenylseleno)ferrocene platinum complexes were also synthesized from triethoxysilane and (undecenylseleno)- or 1,1'-bis(undecenylseleno)ferrocene platinum complex directly. The platinum complexes of ferrocenyl selenoether and polymer-supported ferrocenyl selenoether were efficient catalysts for hydrosilylation of olefins with triethoxysilane. The catalytic activity of polysiloxane-supported platinum complexes (prepared by the method of immobilization after coordination) was similar to those of the corresponding ferrocenyl selenoether platinum complexes and higher than those of catalysts prepared by the method of coordination after immobilization.
