  A synthesis of the unknown azacyclopropenone (azirinone) system was attempted via α-azido ketenes. Treatment of α-azido acid chlorides with triethylamine, in an attempt to generate α-azido ketenes, led in good yield to nitriles containing one less carbon. At −60° it was possible to trap the α-azido ketene 7c with benzalaniline to form a β-lactam. The formation of nitriles most likely proceeds by intermediacy

  尝试通过α-叠氮基烯酮合成未知的氮杂环丙烯酮（叠氮酮）系统。为了产生α-叠氮基烯酮，用三乙胺处理α-叠氮基酰氯导致了含碳量少的腈的高收率。在-60°时，可以用苯并苯胺捕获α-叠氮基乙烯酮7c以形成β-内酰胺。腈的形成最有可能通过叠氮酮的中间进行。反应顺序可将羧酸有效降解为腈，同时损失一个碳。
