Article abstract of DOI:10.1055/s-1991-28409

Novel semicyclic 3-aryl-3-chloro-2-propeniminium perchlorates 6 are synthesized by treating semicyclic enaminones 1 (2-aroylmethylene-1-methylpyrrolidines, -piperidines and -azepanes) with phosphoryl chloride dimethylformamide. Reaction of these chloropro
