摘要:
Ni(COD)(2)/4-ClC6H4COR (R = H, CH3, Ph) was found to be an efficient catalyst system for the addition reactions of arylboroxines with aromatic and aliphatic aldehydes. The catalytically active species for Ni(CCD)(2)/4-ClC6H4COR catalyst systems was likely to be their oxidative addition adducts, 4-RCOC6H4-Ni(II)Cl(COD) complexes. (C) 2009 Elsevier Ltd.
