Palladium-Catalyzed Cross-Coupling Reactions of Vinyl and Aryl Triflates with Tetraarylborates
Ciattini, Pier Giuseppe,Morera, Enrico,Ortar, Giorgio
, p. 4815 - 4818 (2007/10/02)
Sodium tetraarylborates 2 have been found to couple efficiently with vinyl and aryl triflates 1 in the presence of a palladium(0) catalyst to afford arylalkenes and biaryls 3 in good yields and under mild conditions.
