The invention relates to a method for producing mixed-substituted dialkyiphosphinic acids, esters, and salts, characterized in that a) a phosphinic acid source (I) is reacted with olefins (IV) in the presence of a catalyst A to obtain an alkylphosphonous acid, the salt or ester (II) thereof, b) the obtained alkylphosphonous acid, the salt or ester (II) thereof is reacted with an olefin (IV) in the presence of a catalyst B to obtain the mixed-substituted dialkylphosphinic acid derivative (III), wherein R
