SYNTHESIS OF COPPER COMPLEXES OF POLYEP1CHLOROHY- DRIN SUBSTITUTED BY 1MIDAZOLE AND THEIR CATALYSIS FOR OXIDATIVE COUPLING OF 2,6-DIMETHYLPHENOL
咪唑代聚环氧氯丙烷-铜络合物的合成及其对2,6-二甲基苯酚氧化偶合的催化作用

The preparation of polyepichlorohydrin substituted by imidazole from polyepiehlo-rohydrin and lithium imidazolide in aprotic dimethyl sulfoxide was proved successful. These polymeric ligands coordinate with CuCl2 in alcoholic solution rapidly and tend to form complexes with Im/Cu molar ratio equaling to 4. All macromolecular complexes obtained are insoluble in coommn solvents, and in the presence of them, the oxidative coupling of 2,6-dimethylphenol in dichlorobenzen-methanol(6.5/1, V/V) shows both "cooperativity"and "substrate inhibition". So, the reaction takes place by a enzyme-like mechanism.
