The invention relates to a method for producing mono-carboxyfunctionalized dialkylphosphinic acids and esters and salts thereof, characterized in that a) a phosphinic acid source (I) is reacted with olefins (IV) to yield an alkylphosphonic acid, salt or ester (II) thereof in the presence of a catalyst A, b) the alkylphosphonic acid thus obtained, salt or ester (II) thereof is reacted with an α,β-unsaturated carboxylic acid derivative (V) to yield a mono-carboxyfunctionalized dialkylphosphinic acid derivative (III) in the presence of a catalyst B, wherein R
