catalyst for the oxidation of secondary amines under mild conditions using either urea hydrogen peroxide (UHP) or tert-butylhydroperoxide (TBHP) as the oxidant. Under optimized reaction conditions (2 mol % catalyst, 3–4 equiv TBHP, CH2Cl2 as the solvent, 40 °C), the corresponding nitrones were obtained with different efficiency depending on the nature of the cyclic or acyclic amine used.
无机-有机杂化材料[MoO 3(bipy)] [MoO 3(H 2 O)]} n(bipy = 2,2'-bipyridine)可用作耐水催化剂,用于仲胺的氧化在温和条件下,使用过氧化氢脲(UHP)或叔丁基过氧化氢(TBHP)作为氧化剂。在优化的反应条件下(2摩尔%的催化剂,3-4当量的TBHP,CH 2 Cl 2作为溶剂,40°C),根据所用环状或无环胺的性质,可以有效地获得相应的硝酮。
