Abstract

A variety of tertiary silanes, even those with functional substituents, undergo an unprecedented iron-catalyzed dehydrogenative coupling (see scheme) in a convenient approach to disilanes, including unsymmetrical disilanes and polymers with Si-Si bonds in the backbone. Consideration of the catalytic reaction pathway revealed the intermediacy of a hydrido(disilyl)iron(IV) complex.

摘要

各种叔硅烷，即使是带有官能取代基的叔硅烷，都能通过一种方便的方法进行前所未有的铁催化脱氢偶联反应（见反应式），生成乙硅烷，包括不对称乙硅烷和主链中含有硅 - 硅键的聚合物。对催化反应途径的研究揭示了氢（二硅基）铁（IV）配合物的中间体。
