Mechanism of photolysis of benzyl dimethylphenylsilyl ketone: Radical fragmentation versus isomerization

  • Physical Chemistry

Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Conclusions

  1. 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. 2.

    Acetophenone and triphenylene sensitize decomposition of this ketone from its triplet excited state via two competing pathways: isomerization to siloxycarbene and radical fragmentation.
