1-Aryl-1H-1,2,3-triazole-4-carboxamides 7d–f have been synthesized and converted to 2-dimethylamino-4-quinolones 12d–f by flash vacuum thermolysis (FVT). The reaction takes place via carboxamidoketenimine 9 and amidinoketene intermediates 10. The former are observed by FTIR spectroscopy at 77 K or in Ar matrices at 12 K.
1 芳基-1H-1,2,3-三唑-4-甲酰胺 7d-f 已被合成,并通过闪速真空热解(FVT)转化为 2-二甲基氨基-4-喹啉酮 12d-f。反应通过羧酰胺基乙烯亚胺 9 和脒基乙烯中间体 10 进行。前者可在 77 K 或 12 K 的氩基质中通过傅立叶变换红外光谱观察到。
