Oxetane Ring Enlargement through Nucleophilic Trapping of Radical Cations by Acetonitrile

Oxidative electron transfer cycloreversion of trans,trans-2-cyclopropyl-4-methyl-3-phenyloxetane, using triphenylthiapyrylium perchlorate as a photosensitizer, leads to distonic 1,4-radical cations; subsequent cleavage gives rise to fragmentation products (pathway a), whereas nucleophilic trapping b...

description Oxidative electron transfer cycloreversion of trans,trans-2-cyclopropyl-4-methyl-3-phenyloxetane, using triphenylthiapyrylium perchlorate as a photosensitizer, leads to distonic 1,4-radical cations; subsequent cleavage gives rise to fragmentation products (pathway a), whereas nucleophilic trapping by acetonitrile affords a ring expanded oxazine (pathway b).
