✦ Synopsis

Thermolysis of l,l-dimethyl-l-benzyl-2-(iminophenylmethyl)hydrazinium hydroxide inner salt gave dimethylamine, 2,4,6-triphenyl-s-triazine and 2,4,6-triphenyl-1,2-dihydro-s-triazine. Acylaminimides (1) substituted with either a benzy12, ally1 3 or propargy14 group on the quaternary nitrogen undergo facile thermal Stevens-type rearrangements to give hydrazides (2). The mechanistic aspects of have been extensively studied'. these rearrangements RCONfi(Me)2R' b RCONR'N(Me)2
