Synthesis of Crosslinked Polystyrene Supported Platinum Complexes and Their Catalytic Properties for Hydrosilylation

Abstract

Abstract: Mercaptomethylated and crosslinked polystyrene supported platinum complexes were synthesized and used for hydrosilylation as the catalyst, and they have a high activity in hydrosilylation of olefines and acetylenes with dichloromethylsilane(DCMS),particularly for compounds with one conjugated substituent such as styrene, phenyl acetylene and trialkyl vinyl silanes. Hydrosilylation activity is obviously reduced for compounds with electron acceptor groups adjacent to double bond as butyl acrylate, and they have no activity for methyl methacrylate. These catalysts have a good reusability.

Key words: Mercaptomethylated polystyrene-supported platinum complex catalyst, Hydrosilylation, Dichloromethylsilane, Unsaturated compound
