Abstract
Abstract: The photosolvolysis reactions, in methanol, of six substituted benzyl acetates (7a-9 and benzyl pivalates@ a-9 were studied. Five major benzylic products were formed from two critical intermediates. The ethers (9) were formed from the ion pair, 15, and all of the other products (10-f4) were formed from the radical pair, 16. Quenching studies showed that only excited singlet state reactivity was important. The product yields were found to be highly ...
