| Abstract: | Reaction of poly(ethylene glycol) with acetyl chloride,benzoyl chloride and 3,4-dicholo benzoyl chloride in the presence of Et3N readily gave rise to the corresponding PEG bound carboxylic esters,which was treated with different Grignard reagents resulted in the generation of a tertiary alcohol library in good yields and purities with convenient manipulation and easy purification of products.These soluble polymeric reagents exhibited enough reactivity for this reaction under mild conditions.Moreover,it can be regenerated and reused as environmentally benign reagent. |
