Treatment of 3-aryl-1-(tetrazol-5′-yl)triazenes (4) with lead tetra-acetate resulted in a fragmentation to aryl diazocyanides. The triazenes (4) and their monomethyl derivatives when treated with mercuric acetate and phenylmercury hydroxide gave stable mercuri compounds with mercury bonded at N-3 and the tetrazole N-2′. The reaction of the triazenes with acetic anhydride resulted in acetylation of
用四乙酸铅处理3-芳基-1-(四唑-5'-基)三氮烯(4)导致碎片化为芳基重氮氰化物。当用乙酸汞和氢氧化苯汞处理时,三氮烯(4)及其一甲基衍生物得到稳定的汞化合物,其汞键合在N-3和四唑N-2'处。三氮烯与乙酸酐的反应导致三氮烯单元乙酰化,并断裂成芳基重氮离子和5-乙酰氨基四唑。讨论了这些反应并分析了产物的13 C nmr光谱。

Previously claimedstable solid aryldiazoisocyanides were found to be crude arylazides, and dehydration of formamides as a route to stableN-isocyanides must be viewed with caution; stableN-formyltriazenes are confirmed and literature difficulties with reproducible syntheses are explained.
