Conclusions
-
1.
Direct photolysis of benzyl dimethylphenylsilyl ketone occurs from its singlet excited state and intermediate formation of a pair of benzyl and dimethylphenylsilylformyl radicals.
-
2.
Acetophenone and triphenylene sensitize decomposition of this ketone from its triplet excited state via two competing pathways: isomerization to siloxycarbene and radical fragmentation.
