## Abstract A homologous series of __N__‐acylcyanamides of the formula R~2~N−[C(NMe~2~)=N]~__n__~−C(NMe~2~)=O with __n__ = 1−3 has been prepared among similar amino‐substituted __N__‐acyl‐oligonitriles by treatment of guanidine 4 with carbamoyl chloride 5 yielding compound 6 (__n__ = 1) and by ring
