[2-(HALOGENOFORMYL)-VINYL]-ORGANYL-PHOSPHINIC ACID HALIDES OF THE GENERAL FORMULA <IMAGE> in which R1 stands for an alkyl group having 1 to 8 carbon atoms, an aryl group or a substituted derivative of these groups, R2 stands for a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, an aryl group or a substituted derivative of these groups, and X stands for a chlorine or bromine atom, are produced. To this end, a 2 halogenoacrylic acid or a substitution product thereof of the general formula <IMAGE> in which R2 and X have the meanings given above, is reacted at 15 DEG -90 DEG C. with an organyldihalogenophosphane of the general formula R1-PX2 in which R1 and X have the meanings given above.
