Catalytic silicon‐carbon or silicon‐heteroatom bond‐forming hydrosilylation has become increasingly important in synthetic chemistry, catalysis and organosilicon chemistry. Herein we report a platinum‐catalyzed one‐pot and tandem hydrosilylation/cyclization of OH‐containing alkynes with dihydrosilanes, allowing for facile synthesis of six‐membered organosilicon compounds, including silyloxycycles and
在合成化学,催化和有机硅化学中,催化硅碳或硅杂原子键形成的氢化硅烷化作用变得越来越重要。本文中我们报道了含OH的炔烃与二氢硅烷的铂催化一锅法和串联氢化硅烷化/环化反应,可轻松合成六元有机硅化合物,包括甲硅烷基氧环和环状硅氧烷,且产率高且具有良好的立体选择性。
