Abstract

In der vorliegenden Mitteilung wird erstmals ein Zugang zu trans‐N‐Acyl,N‐alkyl‐1‐amino‐1,3‐butadienen 4, sowie zu trans‐N‐Acyl, N‐aryl‐1‐amino‐1,3‐butadienen 4 beschrieben. Deprotonierung von N‐substituierten 1‐Imino‐2‐butenen 2 führt vermutlich zu den nicht isolierten delokalisierten Anionen 3, die anschliessend regioselektiv am Stickstoffatom acyliert werden.
