Ethyl-2,2-difluoro-2-trimethylsilylacetate has been prepared by electrolysis of ethyl-2-chloro-2,2-difluoroacetate in one step, at a molar scale, in the presence of a large excess of chlorotrimethylsilane. The transfer of the ethyl-2,2-difluoroacetate moiety to various electrophiles has been achieved. (C) 2000 Elsevier Science Ltd. All rights reserved.
