Azides (2a-d), in the base catalyzed decomposition with aromatic amines yielded the corresponding N-aryl-N'-alkyl ureas (4a-t) via Curtius rearrangement.However, the base catalyzed decomposition of 2 with phenylhydrazine took place via azido group displacement to afford phthalimido aliphatic acid phenylhydrazides (8a-d).Decomposition of azides (2a-d) in neutral medium yielded the corresponding sym-N,N'-di-alkyl ureas (9a-d), via Curtius rearrangement.
