Oxidative debenzylation of N-benzyl aromatic amines using DMSO as a non-toxic oxidant and catalyzed by TsOH gave N-phenylimines, which were spontaneously hydrolyzed to form anilines and benzaldehydes in good yields. This reaction employs mild, metal-free conditions. The conditions are also suitable for the debenzylation of benzylphenylethers.
使用无毒的 DMSO 作为氧化剂,并在 TsOH 催化下,N-苄基芳香胺经过氧化脱苄反应,得到了 N-苯基亚胺,这些亚胺自发水解形成了苯胺和苯甲醛,产率良好。该反应采用温和、无金属条件。这些条件同样适用于苄基苯基醚的脱苄反应。
