摘要

以一维配位聚合物为催化剂，过氧化叔丁基(TBHP)为氧化剂，在非常温和的条件下，通过氧化偶联反应将苯胺转化为亚胺，收率接近91%。以2,3-吡啶二羧酸(2,3-pydc)和2,2Ꞌ-联吡啶(2,2Ꞌ-bpy)为配体，通过不同的合成工艺重新合成了一维配位聚合物[{Cu2(2,3-pydc)2(2,2 -pydc) (H2O)2}. 4h2o]n(A)，并利用不同的物理化学技术，如红外光谱、紫外-可见光光谱、元素分析和TGDTA分析(包括重建x射线单晶结构)对其进行了表征。提出的反应机理表明，灵活的配位不饱和Cu(II)中心和叔丁基过氧自由基的形成促进了催化反应。

EXPLORATION OF COPPER-BASED COORDINATION POLYMER AS CATALYST: HIGH YIELD OXIDATIVE COUPLING OF BENZYLAMINE TO IMINE

Benzylamine to imine conversion through oxidative coupling reaction has been achieved with almost 91% yield under very mild conditions by applying a one-dimensional coordination polymer as a catalyst and tert-butyl hydroperoxide (TBHP) as an oxidizing agent. The 1D-coordination polymer, [{Cu2(2,3-pydc)2(2,2ʹ-bpy) (H2O)2}.4H2O]n(A) has been re-synthesized by different synthetic process using the ligands 2,3- pyridinedicarboxylic acid (2,3-pydc) and 2,2Ꞌ-bipyridine (2,2Ꞌ-bpy) and it has been characterized by utilizing different physicochemical techniques such as IR-spectroscopy, UV-Vis spectroscopy, elemental analysis and TGDTA analysis including reestablishment of X-ray single crystal structure. The proposed mechanism of the reaction indicates that the catalytic reaction is facilitated by a flexible and coordinatively unsaturated Cu(II) center and through the formation of tert-butyl peroxy radical.
