(C₄H₄N₂H)₂Cr₃O₁₀ has been prepared by the reaction of C₄H₄N₂ with CrO₃ in water. (C₄H₄N₂H)₂Cr₃O₁₀ was identified by elemental analysis, IR, UV-Vis and TG-DTA-TMA system. The oxidation of benzyl alcohol by (C₄H₄N₂H)₂Cr₃O₁₀ in organic solvents showed that the reactivity increased with the increase of the dielectric constant. The oxidation of alcohols was examined by (C₄H₄N₂H)₂Cr₃O₁₀ in CH₂Cl₂. As a resuit, (C₄H₄N₂H)₂Cr₃O₁₀ was found as efficient oxidizing agent that converted benzylic alcohol, allylic alcohol, saturated primary alcohol, secondary alcohols to the corresponding aldehydes or ketones(70%~96%). The selective oxidation of alcohols was also examined by (C₄H₄N₂H)₂Cr₃O₁₀ in CH₂Cl₂. (C₄H₄N₂H)₂Cr₃O₁₀ was selective oxidizing agent(10%~96%) of benzylic alcohol, allylic alcohol, saturated primary alcohols in the presence of secondary ones. In the presence of DMF. solvent with acidic catalyst such as HCl. (C₄H₄N₂H)₂Cr₃O₁₀ oxidized benzyl alcohol and its derivatives. The Hammett reaction constant was -0.70(303K). The observed experimental data were used to rationalize the hydride ion transfer in the rate determining step.
