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.
