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 thus obtained alkyl phosphonic acid, salt, salt or ester (II) thereof is reacted with compounds of formula (V) and/or (VI′) to yield mono-functionalized dialkylphosphinic acid derivatives (VI) and/or (VI′) in the presence of a catalyst B, and c) the thus obtained mono-functionalized dialkylphosphinic acid derivatives (VI) and/or (VI′) are reacted to yield a mono-carboxyfunctionalized dialkylphosphinic acid derivative (III) in the presence of a catalyst C, wherein R
