  Preparation, structure and catalytic activity of copper(II) complexes of novel 4,4′-BOX ligands

  摘要：

  This Letter details the synthesis of two new 4,4'-bisoxazoline (BOX) ligands. The copper(II) complex of one of the new ligands is structurally determined. The catalytic performance of the copper(II) complexes of the novel ligands, and that of our recently described phenyl AraBOX ligand in Diels-Alder reactions are reported. We have used the structural information to propose an explanation of a curious variation in the diastereoselectivity obtained in the case of one ligand complex. (C) 2010 Elsevier Ltd.

  4,4′BOX based catalysts: Synthesis, structure and catalytic application

  摘要：

  The synthesis of two new 4,4 ' bisoxazoline ligands is described. The use of copper complexes of these and three other recently described related ligands as catalysts in a cyclopropanation reaction is discussed. The first structural data on one such chiral copper complex is reported herein. (C) 2010 Elsevier B.V. All rights reserved.
