摘要

Photosensitized reactions of 2, 2-diaryloxetanes by 1, 4-dicyanonaphthalene, 1- cyanonaphthalene, and 9, 10-dicyanoanthracene, which give such ring-cleavage products as substituted benzophenones and alkenes, have been investigated. Quantum yields for the ring cleavage vary with the substituents on both the aryl group and oxetane ring. The quantum yield increases with increase in electron-donating ability of the oxetane. The ...
