具有不同长度碳链的不对称四苯基卟啉及其金属配合物的合成

叶绿素、血红素、维生素B_(12)等都是不对称的金属卟啉类化合物叫,1975年Anton等首次合成了几种不对称取代四苯基卟啉及其金属配合物.其后,Leznoff,Molinaro等也发表了有关工作.我们模拟叶绿素的结构合成了三个系列13个具有不同长度碳链的单取代四苯基卟啉及其铜、锌、钴、镍等金属配合物(图1).用元素分析、红外光谱、可见吸收光谱和核磁共振谱等表征了它们的可能结构.

The synthesis of asymmetrically substituted porphyrins and their metal complexes

Three unsymmetrically substituted porphyrins, namely 5-(4-n- amyloxyphenyl) 10, 15, 20-triphenyl porphenyl porphyrin and 5-(4- n-decyloxyphenyl) 10, 15, 20-triphenyl porphyrin, 5-(4-n- hexadecyloxyphenyl) 10, 15, i0-triphenyl porphyrin were synthesised. Reaction of these compounds with copper, zinc, cobalt and nickel salt gave the metal complexes. These compounds were characterized by elemental analyses, IR, visible and NMR spectra.
