Selenoether Ligand Assisted Heck Catalysis. — The reaction of aryl bromides with butyl acrylate or styrene is catalyzed effectively by the catalyst, generated in situ from (I) and PdCl2, or by the pre-made catalysts (II) or (III). The reaction conditions are not suitable for aryl chlorides. Addition of Bu4NBr allows the preparation of (VI) from 4-chloroacetophenone (VII), albeit with low yields. — (CHAKRABORTY, T.; SRIVASTAVA, K.; SINGH*, H. B.; BUTCHER, R. J.; J. Organomet.
