A novel photoinduced bromination of benzylsilanes is reported. This reaction undergoes smoothly under UV irradiation at room temperature via two key steps: C—Si bond cleavage and subsequent bromination, which presents a new protocol to the synthesis of benzyl bromides. In addition, a possible mechanism of this reaction is proposed.

Key words: photochemistry, bromination, mechanism, radical reactions, organicsilanes
