Methoxycarbonylketene 4a, methoxycarbonyl(methyl)ketene 4b, chloroketene 4c, cyanoketene 4d, diphenylketene 4e, and 2-pyridylketene 4f have been generated by flash vacuum thermolysis of the corresponding 2-pyridylacetamide derivatives 3a–f and isolated in Ar matrices for FT-IR spectroscopic characterisation. The N-(2-pyridyl)-2-pyridylacetamide 3f yielded 2-pyridyl isocyanate in addition to 2-pyridylketene
Methoxycarbonylketene图4a,甲氧基羰基(甲基)乙烯酮4b中,chloroketene 4c中,cyanoketene 4D,二苯基乙烯酮4E和2- pyridylketene 4F已经由相应的2- pyridylacetamide衍生物的闪光真空热解产生图3a - ˚F和Ar中分离矩阵为FT-IR光谱表征。的N-(2-吡啶基)-2- pyridylacetamide 3F除了2- pyridylketene得到2-吡啶基异氰酸酯。
