Reaction of Dry Arenediazonium o-Benezendisulfonimides with Triorganoindium Compounds

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
