Abstract

The palladium-catalyzed cross-coupling reaction between various arenediazonium o-benzenedisulfonimides and aryltin derivatives is described. The procedure is general, easy and gives pure biaryls in good yields (25 examples, average yield 79%). o-Benzenedisulfonimide can be recovered (>80%) and reused to prepare again the starting material.
