摘要:
Oxidation of chromium and molybdenum arenetricarbonyl complexes AreneM(CO)(3) with tertbutyl hydroperoxide (ROOH) in aprotic solvents such as heptane, aromatic hydrocarbons, dioxane, and in methanol (R'OH). Kinetic characteristics of the oxidation reaction, its rate, the composition and properties of the metal-containing products, and the yield of CO and CO2 gases were found to depend on the acidity of the solvent used. The effect of the solvent nature was explained in terms of the proposed mechanism of AreneM(CO)(3) oxidation involving the formation of AreneM(CO)(3) . 2ROOH complexes in aprotic solvents and AreneM(CO)(3)(R'OH . ROOH) complexes in methanol and their further conversion into the reaction products by one-electron transfer route or through the stage of the metal complex protonation.
