Efficient Protosilylation of Unsaturated Compounds with Silylboronates over a Heterogeneous Cu₃N Nanocube Catalyst

Abstract

Copper-catalyzed protosilylation of unsaturated compounds with silylboronates has attracted attention for the production of organosilanes; however, the use of organic ligands or bases is unavoidable. Herein, we report a heterogeneous catalytic system for the protosilylation of unsaturated compounds with silylboronates under mild and additive-free conditions over copper nitride nanocubes (Cu₃N NCs). This method can be applied to various substrates (e.g., alkynes, alkenes, or imines) to afford the corresponding organosilicon compounds. The Cu₃N NC catalyst can be easily recovered and reused several times. Thus, the active and reusable Cu₃N NC catalyst offers a green and sustainable method for efficient organosilane production.

Key words
