General description

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

Application

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

An efficient preparation of pure ethyl Z- and E-alpha,alpha-difluoro-4-phenyl-3-butenoate 1a and 1b together with the corresponding acids 2a and 2b is described. The procedures involve stereocontrolled additions of *CF2CO2Et to phenylacetylene or beta-bromostyrene. Compound 1a is easily obtained by addition
