Abstract

A linear polymer containing Co(Salphen) was synthesized by Suzuki coupling with bromine-containing Co(Salphen) and 1,4-benzenediboronic acid. The molecular weight was determined by gel per-meation chromatography. The polymer was used to catalyze the oxidation of 2,3,6-trimethylphenol, the conversion of 2,3,6-trimethylphenol could reach 99% at 24 h and the catalyst could be re-cycled for 3 times without significant reduction in conversion.

摘 要

以含溴的Co(Salphen) (双水杨醛缩邻苯二胺合钴)和1,4-苯二硼酸通过Suzuki偶联合成了一种含有Co(Salphen)的线型聚合物，其分子量通过凝胶渗透色谱测定，该聚合物用于催化2,3,6-三甲基苯酚氧化，24 h 2,3,6-三甲基苯酚的转化率可以达到99%，且该催化剂可以循环使用3次无明显的转化率和选择性下降。
