摘要
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 R1, R2, R3, R4, R11, R12, R13, R14 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 represents H, C1-C18-alkyl, C8-C18-aryl, C6-C18-aralkyl, C8-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, catalyst A represents transition metals and/or transition metal compounds and/or catalyst systems composed of a transition metal and/or a transition metal compound and at least one ligand, and catalyst B represents compounds forming peroxides, and/or peroxo compounds, and/or azo compounds.
