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

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.
