Previously claimed stable solid aryldiazoisocyanides were found to be crude arylazides, and dehydration of formamides as a route to stable N-isocyanides must be viewed with caution; stable N-formyltriazenes are confirmed and literature difficulties with reproducible syntheses are explained.
发现先前要求保护的稳定的固态芳基重氮异氰酸酯是粗制的芳基叠氮化物,必须谨慎地观察甲酰胺的脱水作为稳定的N-异氰酸酯的途径。证实了稳定的N-甲酰基三氮烯,并解释了可重复合成的文献困难。
