Borane-Catalyzed Intermolecular Aryl Transfer between Hydrosilanes: Shifting the Equilibrium by Removal of a Gaseous Hydrosilane

The preparation of organosilanes is indeed far from trivial, despite their vast application. Herein, we report a straightforward and general hydrosilane iterative evolution system for the on-demand synthesis of heteroleptic-substituted hydrosilanes. A series of previously difficult-to-prepare hydrosilanes with two or three diverse substituents were readily obtained. Our process is achieved just by using a catalytic amount of BH
