various fruitful organic reactions such as a catalytic Mitsunobu reaction were reported by virtue of alkyl 2-phenylazocarboxylates, however, the synthesis of alkyl 2-phenylazocarboxylates largely depended on the stoichiometric use of toxic oxidants. In this manuscript, an environment-friendly aerobic oxidative transformation of alkyl 2-phenylhydrazinecarboxylates to alkyl 2-phenylazocarboxylates is
近来,由于2-苯基偶氮羧酸烷基酯,报道了各种富有成效的有机反应,例如催化的Mitsunobu反应,但是,2-苯基偶氮羧酸烷基酯的合成很大程度上取决于有毒氧化剂的化学计量使用。在该手稿中,公开了一种环境友好的2-苯基肼甲酸烷基酯的好氧氧化转化为2-苯基偶氮羧酸烷基酯的方法。在温和条件下,使用CuCl和DMAP系统可有效催化2-苯基肼甲酸烷基酯的需氧氧化。本发明的铜催化反应速率比以前报道的铁催化速率快得多,并且在3小时内合成了多种偶氮产物。本协议在更大范围内是有效的。
