[摘要]：The diaryldiazenes (19 examples) and aryl(tert-butyl)diazenes (3 examples) 3 were prepared by electrophilic C-coupling reactions of dry arenediazonium o-benzenedisulfonimides 1 with Grignard reagents. The reactions were carried out in anhyd THF at -78 degrees C under nitrogen and gave diazenes in 66-91% yield with few exceptions. In all cases the anion precursor of salts 1, i.e. the o-benzenedisulfonimide, was recovered easily, in greater than 90% yield.
