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