Paragraph 0077-0084, (2020/05/01)
The method comprises the following steps, adding a reducing agent water solution :S1. to a reactor: slowly dropwise adding a reducing agent aqueous solution to obtain the diepoxide, adding a reducing agent aqueous solution to the reactor, to obtain the diepoxy, and separating and purifying ;S2. from the organic phase: by one-pot reaction, and adding a reducing agent water, through a pot method to obtain the diepoxide crude solution, to obtain the diepoxide compound. The invention discloses a method for separating and purifying a diepoxide crude product through a high vacuum, distillation . The method comprises the following steps of: adding a reducing agent aqueous solution to the, reactor at a low temperature, to obtain a diepoxide 91% crude, product through 95% a, one-pot reaction, of the diolefin and the m-chloroperoxybenzoic acid solution to obtain a diepoxide crude product solution.

Interest in dinuclear CuII μ-thiolate and CuI disulfide complexes is triggered by their similarity with the CuA site and the possibility to control this redox equilibrium. Three new disulfide ligands L1, L3 and L4 were synthesized and reacted with CuI salts to investigate whether thiolate or disulfide species would form. The nature of L1 precludes the formation of CuII μ-thiolate species, resulting in the formation of [Cu2I(L1)(CH3CN)](BF4)2 which was characterized via single crystal X-ray crystallography. Pyrazole-containing ligands L3 and L4 form CuI complexes that are stable in solution in air for hours with half-wave potentials of approximately +0.55 V versus Ag/AgCl, indicating high stability of the CuI state rather than the CuII state. The half-wave potentials of the CuI complexes with L1 and L2 are less positive, indicating that in order to allow formation of both CuII μ-thiolate and CuI disulfide species, a half-wave potential of roughly 0 V versus Ag/AgCl would be ideal. Furthermore, CuII crystal structures with L1, L2, L3 and L4 and different counterions were compared and analyzed. Pyrazolyl-containing ligands L3 and L4 form complexes that are very similar to the complexes with pyridyl-containing ligands L1 and L2.
