A Lewis acid-catalyzed, solvent-free hydroxyethylation strategy that converts phenols into phenoxyethanol esters is reported. Ethylene glycol diesters are used as renewable and safe alternatives to the harmful ethylene oxide. Oligomerization byproducts from ethylene oxide are also avoided. Applications are demonstrated in upcycling of polyester plastics and preparation of bioactive chemicals.
