Preparation of Diazenes by Electrophilic C-Coupling Reactions of Dry Arenediazonium o-Benzenedisulfonimides with Grignard Reagents. -Twenty-three different aryldiazenes (III) are prepared by electrophilic C-coupling reactions of highly pure and stable salts (I) with Grignard reagents. Work-up temp.
Kinetic investigation of azo coupling reactions between naphthols and 4-methoxy-and 4-nitrobenzenediazonium obenzenedisulfonimides has been carried out for comparison with the related benzenediazonium tetrafluoroborates. The data clearly indicate that the two kinds of diazonium salts show very simil
