The catalytic oxidation of α-ketotriazoles to α,β-diketotriazoles was performed with CuCl2 or CuI/2,9-dimethyl-1,10-phenanthroline in air at 80 °C in good yields. Studies showed that the triazole group participates in complexation to the copper and favors oxidation.
用 CuCl2 或 CuI/2,9-二甲基-1,10-菲咯啉在 80°C 的空气中以良好的产率将 α-酮三唑催化氧化为 α,β-二酮三唑。研究表明,三唑基团参与与铜的络合并有利于氧化。
