摘要：The invention relates to a method for producing monocarboxy-functionalizeddialkylphosphinic 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 analkylphosphonous 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 orwith an oxidizing agent and water or with oxygen and water in the presence of a catalystB to obtain the alkylphosphonic acid derivative (III), wherein R, R, R, Rare identical ordifferent from each other and independently represent, inter alia, H, C-C-alkyl, C-C-aryl,C-C-aralkyl, C-C-alkylaryl, X and Y are identical or different from each other andindependently represent H, C-C-alkyl, C-C-aryl, C-C-aralkyl, C-C-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 metals and/or transition metal compounds and/orcatalyst systems composed of a transition metal and/or a transition metal compound andat least one ligand.
