Abstract

Hydrogen atom abstraction from 1-carbamoyl-1-methylcyclohexa-2, 5-dienes generated the corresponding delocalised 1-carbamoyl-1-methylcyclohexa-2, 5-dienyl radicals at temperatures below ca. 300 K. At higher temperatures suitably substituted examples dissociated to produce toluene and aminoacyl (carbamoyl) radicals. Both types of intermediate were detected and characterised in solution by EPR spectroscopy. From ...
