摘要

两种新的氧化钒（V）配合物[VO2L1]（1）和[V2O2(μ-O)2L2)]（2），其中 L1 和 L2 分别是 5-溴-2-(((2-(吡咯烷-1-基)乙基)亚氨基)甲基)苯酚（HL1）和 5-溴-2-(((2-((2-羟乙基)氨基)乙基)亚氨基)甲基)苯酚（HL2）的去质子化形式、分别合成，并通过物理化学方法和单晶 X 射线测定对其结构进行了表征。X 射线分析表明，络合物 1 中的 V 原子呈方形金字塔配位，络合物 2 中的 V 原子呈八面体配位。复合物的晶体结构通过氢键得以稳定。评估了这些配合物对苯乙烯环氧化反应的催化性能。

Synthesis, Crystal Structures and Catalytic Oxidation Property of Two Oxidovanadium(V) Complexes with Schiff bases.

Two new oxidovanadium(V) complexes, [VO2L1] (1) and [V2O2(μ-O)2L2)] (2), where L1 and L2 are the deprotonated form of 5-bromo-2-(((2-(pyrrolidin-1-yl)ethyl)imino)methyl)phenol (HL1) and 5-bromo-2-(((2-((2-hydroxyethyl)amino)ethyl)imino)methyl)phenol (HL2), respectively, have been synthesized and structurally characterized by physico-chemical methods and single crystal X-ray determination. X-ray analysis indicates that the V atom in complex 1 is in square pyramidal coordination, and those in complex 2 are in octahedral coordination. Crystal structures of the complexes are stabilized by hydrogen bonds. The catalytic property for epoxidation of styrene by the complexes was evaluated.
