A catalytic, metal-free O–H bond insertion of α-diazoesters in water in the presence of B(C6F5)3·nH2O (2 mol %) was developed, affording a series of α-hydroxyesters in good to excellent yields. The reaction features easy operation and wide substrate scope, and importantly, no metal is needed as compared with the conventional methods. Significantly, this approach further expands the applications of
在存在B(C 6 F 5)3 · n H 2 O(2摩尔%)的条件下,开发了水中无催化的α-重氮酸酯插入金属的O–H键,从而获得了一系列的α-羟基酯。好到极好的产量。该反应具有易于操作和广泛的底物范围的特点,重要的是,与常规方法相比,不需要金属。重要的是,这种方法进一步扩展了B(C 6 F 5)3在耐水条件下的应用。
