Aliphatic Hydrosilanes via Nickel-Catalyzed Reductive Csp³–Si Coupling of Primary Alkyl Bromides and Chlorohydrosilanes

Abstract

The reductive C–Si coupling of chlorosilanes offers efficient access to organosilanes, but its potential for constructing aliphatic ones remains largely unexplored. This manuscript presents a nickel-catalyzed Csp 3 –Si coupling reaction of unactivated alkyl–Br and R 2 Si(H)Cl. This work establishes a new approach for synthesizing highly functionalized aliphatic hydrosilanes from readily available chemical feedstocks. The reaction is easily scalable and can accommodate various functional groups, including carboxylic acids, which are usually incompatible with basic conditions.
