摘要：

Imidoyl radicals 4a-d, obtained by hydrogen abstraction from imines 1a-d, give 7-membered cyclisation leading to oxazapines 2a-d. The intermediate spirocyclohexadienyl radicals of the competitive 6-membered ring closure (6a-d) rearrange to aryloxy radicals, giving benzophenones 3a-d: the whole process entails a novel 1,5-aryl radical translocation from an oxygen to a carbon atom.
