| Abstract: | A silica-supported arsine palladium(0) complex has been prepared from γ-chloropropyltriethoxysilane via immobilization on fumed silica, followed by reaction with potassium diphenylarsenide and palladium chloride, and then reduction with hydrazine hydrate. The complex exhibited good activity in phenylation reaction of acid chlorides and aryl iodides by sodium tetraphenylborate. This polymeric palla-dium(0) catalyst was stable and could be reused without noticeable loss of activity. |
