合成了4种金属的四羧酸酞菁金属(Metal Phthalocyanine Tetracarboxylic Acid,M-PTC)配合物,利用红外光谱、紫外光谱及X射线晶体衍射分析对配合物结构进行了表征.以其作为催化剂,开展了以分子氧为氧源的烯烃环氧化的研究.考察了反应体系中溶剂、温度、时间、溶剂用量、共还原剂用量以及催化剂用量对反应的影响.其中Fe-PTC催化活性最好,在n(环辛烯)∶n(催化剂)∶n(共还原剂)=4∶0.002 5∶16、溶剂(1,2-二氯乙烷)12 mL、温度45℃和反应时间5h条件下,环辛烯转化率达到100％,环氧环辛烷的选择性为91.1％,催化剂活性TON值达到1457.催化剂循环使用7次后,其结构和活性无明显变化.
