Simple heating of mixtures of N-arylcycloheptatriene-1-imines and acyl chlorides in the presence of an excess amount of triethylamine afforded 1-azaazulen-2(1H)-ones in high yields.The intermediacy of the <8+2> cycloadducts between the 2,4,6-cycloheptatriene-1-imines and ketenes were confirmed by their isolations.Analogous results were obtained with tropone hydrazones.
