Abstract:
Chlorosilanes are versatile reagents in organic synthesis and material science. A mild pathway is now reported for the quantitative conversion of hydrosilanes to silyl chlorides under visible‐light irradiation using neutral eosin Y as a hydrogen‐atom‐transfer photocatalyst and dichloromethane as a chlorinating agent. Stepwise chlorination of di‐ and trihydrosilanes was achieved in a highly selective fashion assisted by continuous‐flow micro‐tubing reactors. The ability to access silyl radicals using photocatalytic Si−H activation promoted by eosin Y offers new perspectives for the synthesis of valuable silicon reagents in a convenient and green manner.
