The coordination chemistry of copper(II) complexes bearing pyridine-oxazoline (“Pyox”) ligands has been studied, with an aim of investigating their catalytic ability. Interestingly, the stability of the coordinated ligands has been shown to be much less than previously assumed: hydrolysis of the ligands by fortuitous water gives rise to 2-pyridine carboxylate formation, which encapsulate the copper
已经研究了带有吡啶-恶唑啉(“ Pyox”)配体的铜(II)配合物的配位化学,旨在研究其催化能力。有趣的是,已证明配位配体的稳定性远低于先前的假设:偶然的水使配体水解会生成2-吡啶羧酸盐,从而将铜包封在二维配位聚合物3中。 [Cu(R-Pyox)(NCMe)2(ClO4)2] R =苄基(Bn)2a,苯基(Ph)2b,异丙基(iPr)2c}的制备,其中的苄基衍生物已通过CW EPR光谱。配合物[Cu(Bn-Pyox)(NCMe)2(ClO 4)2]和上述配位聚合物已经在晶体学上进行了表征。
