Conjugate Addition of Aryl Boronic Acids to Enones Catalyzed by Cationic Palladium(II)-Phosphane Complexes

A cationic palladium complex was found to be an efficient catalyst for the 1,4‐addition of aryl boronic acids to enones at room temperature (see scheme; X=ClO4, OTf, BF4, PF6, or SbF6); Tf=trifluoromethanesulfonyl).
