Abstract A new method for the preparation of aromatic diazene derivatives 3a—1, 5, 7a, b, 9 under very mild conditions is described. The reaction of trialkylarylstannanes with nitro- substituted benzenediazonium tetrafluoroborates leads, by strict ipso substitution, to the corresponding diaryldiazenes in satisfactory to high yields. Due to the excellent leaving group quality of the stannyl group azo compounds may be prepared which are not ...
