Synthesis of novel binuclear Cu(II) complex and its application as catalyst for conversion of amine to imine

Abstract

Oxidative coupling reaction of benzylamine to imine has been achieved with almost 90% yield under very mild reaction conditions by applying a novel binuclear Cu(II) complex as a catalyst. Binuclear Cu(II) complex, [Cu2(2,3-pydc)(2,2ꞌ- bpy)4](ClO4)2.2H2O [A] has been synthesised using the ligands 2,3-pyridinedicarboxylic acid (2,3-pydc) and 2,2ꞌ-bipyridine (2,2ꞌ-bpy). The newly synthesised catalyst has been characterised by using single crystal X-ray diffraction study (SC-XRD), UV-Vis spectroscopy, IR-spectroscopy and elemental analysis.
