Site-selective C–H functionalization of silanes is challenging because of the presence of multiple C–H bonds in the same molecule. Now a general photocatalytic site-selective radical functionalization of organosilicon compounds is reported, enabled by the β-silicon effect, which activates β-C(sp3)–H bonds. These reactions are applicable to linear and complex cyclic silanes.
