Patent number: 9018413
Abstract: The invention relates to a method for producing monocarboxy-functionalized dialkylphosphinic 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, and b) the obtained alkylphosphonous acid, the salt or ester (II) thereof is reacted with an oxidizing agent or with an oxidizing agent and water or with oxygen and water in the presence of a catalyst B to obtain the alkylphosphonic acid derivative (III), wherein R1, R2, R3, R4 are identical or different from each other and independently represent, inter alia, H, C1-C18-alkyl, C6-C18-aryl, C6-C18-aralkyl, C6-C18-alkylaryl, X and Y are identical or different from each other and independently represent H, C1-C18-alkyl, C6-C18-aryl, C6-C18-aralkyl, C6-C18-alkylaryl, Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Cu, Ni, Li, Na, K and/or a protonated nitrogenous base, and catalysts A and B are transition met
