Abstract

Some o-phenoxy-and o-anilino-substituted aryliminyl radicals have been generated by thermal decomposition of suitable tert-butyl iminoxyperacetates. The iminyls show no disposition to give 7-membered cyclisation on the phenyl group. In some cases, products have been found that can be rationalised through a 1, 6-spirocyclisation of the iminyl radicals followed by homolytic 1, 5-migration of the phenyl group from the aminic to the ...
