Red Light and Supersilane: A Novel Pathway for Hydrofunctionalizations and Giese Reactions.

Abstract

Herein, we describe the photoredox activation of silanes under deep-red irradiation with or without osmium-based photocatalysts to generate silyl radicals. These radicals were further employed for achieving various reactivities previously unexplored in the red-light spectral region, such as hydrosilylation, hydrosulfonylation, and Giese reaction. Overall, the developed deep-red protocols allow for the preparation of a diverse array of high-value molecules.
