Recoverable multiphase enantioselective catalytic systems for the Kharasch-Sosnovsky oxidation of cycloalkenes with tert-butyl peroxybenzoate are described, based on the use of [BMIM][PF(6)] and a new solvent derived from glycerol as the catalyst reservoir phases, and chiral copper complexes with different ligands from the bis(oxazoline) family. The best results are obtained with the glycerol-derived solvent and a recently described azabisoxazoline-based ditopic ligand, allowing up to four uses of the catalytic phase with good results.
可回收多相手性催化体系用于环烯烃的 Kharasch-Sosnovsky 过氧苯甲酸叔丁酯氧化反应，该体系基于使用 [BMIM][PF6]和一种新型溶剂（由甘油衍生而来）作为催化剂储存相，以及手性铜配合物与双（恶唑啉）家族的不同配体。在甘油衍生溶剂和最近描述的基于氮杂双恶唑啉的双齿配体的作用下，得到了最佳结果，允许催化相重复使用四次，效果良好。
