【摘要】 γ-氯丙基三氯硅烷是生产硅烷偶联剂的重要中间体,主要通过铂络合物催化氯丙烯和三氯氢硅的硅氢化反应来制备,产业规模早已突破万吨级别。但选择性较低、副产物过多是该产品产业化过程中急需解决的一个关键问题。通过铂催化剂的配体修饰以及催化剂负载的方式,科研工作者在发展高活性高选择性的铂络合物催化剂方面取得了较大成果。本文从均相催化剂以及非均相催化剂两个方面,分别概述了近年来催化该硅氢化反应的铂络合物催化剂和反应机理的研究进展,并对更为高效的铂络合物催化剂的发展进行了展望。更多还原

【Abstract】 As an important intermediate for the production of silane coupling agent,γ-chloropropyl trichlorosilane is mainly obtained by Pt catalyzed hydrosilylation of allyl chloride and trichlorosilane.The industrial scale of γ-chloropropyl trichlorosilane has already exceeded 10000 tons.Despite great success achieved in this field,the hydrosilylation reaction is often accompanied with the low selectivity and high amounts of byproducts.Much progress in this hydrosilylation reaction has been made through the modulation of ligands on platinum complexes and their immobilization during the past decades.This paper reviews the progress in platinum complexes used as catalysts in the hydrosilylation reaction of trichlorosilane and allyl chloride,particularly focus on the impacts of ligands to soluble homogeneous platinum complex catalysts and supported platinum complex catalysts.Meanwhile,the progress in its reaction mechanism is presented.At last,some ideas are provided for future research.更多还原
