Abstract: Polystyrene-supported selenoethers were synthesized from chloromethylated crosslinked polystyrene and(HOCH2CH2)2Se or EtOCH2CH2SeCH2CH2OH via Williamson reaction. They were reacted with potassium chloroplatinite in acetone under nitrogen atmosphere to give title complexes. It was found that the platinum complexes exhibited high catalytic activity in the hydrosilylation of olefins with triethoxysilane.

Key words: polystyrene, supported selenoether, platinum coodination, hydrosilylation catalyst, platinum complex
