Pd-catalyzed desulfonylative homocoupling of arenesulfonyl chlorides in the presence of hexamethyldisilane forming biaryls

Add time:09/08/2019    Source:sciencedirect.com

Arenesulfonyl chlorides undergo desulfonylative homo-coupling upon heating with hexamethyldisilane in the presence of Pd2(dibenzylideneacetone)3·CHCl3 as a precatalyst to afford biaryls. Diaryl sulfides are occasionally formed as byproducts.
