A metal-free photocatalytic hydrosilylation of alkenes through the selective activation of Si—H bond has been developed utilizing the readily available and cheaper bromide salt as the catalytic hydrogen atom transfer (HAT) reagent. This protocol features excellent functional group tolerance and broad substrate scope, affording the organosilicon compounds in moderate to excellent yields under a mild and redox-neutral process. This strategy was successfully applied for the introduction of the silyl group into bio-relevant active molecules.
