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‐Benzenedisulfonimide can be recovered and reused to prepare additional arenediazonium o‐benzenedisulfonimides.

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
