A novel transformation involving phosphinediazo ester zwitterions (generated from dialkyl azodicarboxylates with Ph 3 P) and α ‐(alkoxycarbonyl)imidoyl chlorides (prepared from α ‐addition of acyl chlorides to alkyl isocyanides) to afford dialkyl 2‐[3‐alkoxy‐1‐(alkylimino)‐1‐chloro‐3‐oxopropan‐2‐ylidene]hydrazine‐1,1‐dicarboxylates in moderate yields, is described.
