Recently, separation and recycling of the expensive chiral catalysts utilizing soluble PEG (polyethylene glycol) polymer supports have attracted a great of interest.8 The prominent advantage of PEG-immobilized chiral catalysts lies in that they are soluble in organic solvents, thereby allowing the reaction to proceed homogeneously and display similar activities and enantioselectivities to those of the homogeneous parent systems. The recovery of the PEG-supported catalyst from the reaction mixture can be readily achieved by filtration, precipitation or extraction.原話是這樣的,如果PEG都溶于反應體系了,后面如何分離呢,怎樣還能沉淀,抽濾呢 |
