General description

Ethyl chlorodifluoroacetate (ECDFA) undergoes Reformatskii reaction with various aldehydes in DMF.[1] It reacts with phenylacetylene to afford ethyl α,α−difluoro-4-phenyl-3-butenoates.[2]

Application

Ethyl chlorodifluoroacetate (ECDFA) may be used as a starting reagent in the synthesis of 3-gem-difluoro-2-ethoxy allylic alcohols.[3]
