Abstract
Arene and phenylmethanesulfonyl chlorides can be cross-coupled with aryl, heteroaryl, and alkenylstannanes with desulfitation in the presence of 10 mol% CuBr⊙ Me2S, 1.5 mol% Pd2dba3, and 5 mol% tri-2-furylphosphine in tetrahydrofuran or toluene under reflux. This extension of the Stille cross-coupling reaction realizes a new and economical method for the generation of CC bonds. The palladium-catalyzed carbonylative Stille cross-coupling ...
