摘要:
A new method has been developed for the synthesis of alkylaryldiazene oxides by the reactions of t-BuNHMgBr with nitrobenzenes. The cis-azoxy compound 1-tert-butyl-2-(2-chlorophenyl)diazene-2-oxide, which irreversibly isomerizes to the trans isomer upon heating, was obtained for the first time under chemical reaction conditions.
