The singlet 1,1‐diradical ( 1 B 1 ) state of a silylene plays a key role in its photoreactions with benzenes and alkenes, even though similar 1 B 1 states are rarely encountered in carbene chemistry. The photochemical addition to alkenes should be stepwise and the ring closure of the intermediate singlet 1,3‐diradicals was very facile with rates ( k c ) of more than 10 9 s −1 (see scheme).
