摘要: 我们在合成1-甲基-3,5-二苯基吡唑(MDPP)的过程中,发现氯化铜、氯化钴等化合物对1-甲基-3,5-二苯基吡唑啉(H2MDPP)的氧化脱氢反应具有优异的催化性能,对以氯化铜为催化剂的反应机理进行了初步研究,获得了反应过程中形成铜(Ⅱ)H2MDPP、铜(Ⅱ)MDPP和铜(Ⅱ)H2MDPP分子氧配合物的证据。另外,在催化氧化反应体系中曾检测到一价铜,这显然是氯化铜的还原产物,故本文对氯化铜与H2MDPP的计量反应及在催化反应中氧分子参与作用的阶段进行了研究。

Abstract: Stoichiometric reaction of cupric chloride with 1 -methyl-3,5-diphcnylpyrazo-line(H2MDPP) has been studied. It has been found that the chief product of the reaction closely resembles to a catalytic oxidation. From the Stoichiometric reaction mixture a coppcr(Ⅰ) complex of H2MDPPand 1-mcthy1-3,5-diphenylpyrazole (MDPP) has been isolated. The composition and IRspectrum of the complex have been obtained.It has been proved that the stage of reaction with the oxygen' s participation took place before the reduction of coppcr(Ⅱ) to copper(Ⅰ) by the measurement of oxygen consumption in the reaction.
