Photoreactions of(2-Alkoxymethylphenyl)pentamethyldisilanes

摘要

Photolysis of(2-hydroxymethylphenyl)pentamethyldisilane 1 in methanol provides a novel intramolecular photoproduct 4 via silene intermediate 2 but the photoreaction of(2-acetoxymethyl-or allyloxymethylphenyl)pentamethyldisilanes 5 or 10 in methanol affords unexpected photoproducts 8 or 13,respectively,instead of expected intramolecular photoproducts.
