The IR spectra of the resulting products showed that the same functional group, acyl fluoride, could be formed in both reduction processes. The results of 19 F NMR and UV vis spectra revealed that there were other different functional groups formed in the two reduction processes. In the electro chemical reduction , conjunctive double bonds could be formed in the same and different carbon ring. In the chemical reduction, using Zn and Mg as reducing agents, aromatic structure was formed in the products.展开更多

It is much conve-nient to use the oxidant for the epoxidation of carbon carbon double bonds in some unsaturat-ed natural products. Five unsaturated compounds were oxidized to the corresponding epox-ides with dimethyldioxirane and the reaction selectivity was discussed.展开更多
