✦ Synopsis

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 similar reactivities. This fact emphasizes that arenediazonium o-benzenedisulfonimides, which are very stable, may be used as alternatives to the more usual diazonium salts. The azo coupling reactions between 4-nitro-

## Abstract The reaction between various arenediazonium __o__‐benzenedisulfonimides and triorganoindium compounds is described. Depending on the reaction conditions, it is possible to obtain biaryls (16 examples, average yield of 79 %) or diaryldiazenes (18 examples, average yield of 81 %). __o__‐B
