Abstract: The invention relates to a method for the production of an alkenyl phosphonic acid derivative by reacting a phosphonic acid derivative with an alkine in the presence of a complex catalyst system and a base, the conjugated acid of which has a pKa value in dimethylsulfoxide (25ºC, 1 bar) of at least 6.
