Abstract: The invention relates to a process for the preparation of derivatives of dichloroacetic acid esters, by reaction of a glyoxylic acid ester having the general formula R1-CO-COOR2, wherein R1 represents an optionally substituted aryl or heteroaryl group and R2 an alkyl, cycloalkyl or aryl group, with phosphoruspentachloride in ?e presence of a dispersant suitable for distributing the phosphoruspentachloride.
