A mild, efficient, general, and green method for the regenerationof carbonyl compounds from their corresponding oximes is described.Cupric salts promoted hydrolysis of oximes was studied, and thebest reaction conditions for the hydrolysis have been found. Carbonylcompounds were obtained in 85-98% yields afterthe treatment of oximes with 2 molar equivalent of CuCl 2 ˙2H 2 Oat reflux (around 75 ˚C) in
描述了一种温和、高效、通用、绿色的羰基化合物由相应肟再生的方法。研究了铜盐促进肟水解,找到了水解的最佳反应条件。在乙腈和水 (4:1) 的混合溶剂中,用 2 摩尔当量的 CuCl 2 ˙2H 2 Oat 回流(约 75°C)处理肟后,羰基化合物的产率为 85-98%。此外,通过 Cu(OH) 2 ˙2H 2 O 的完全沉淀,可以很容易地以几乎定量的收率回收铜盐。
