| titleOfInvention | Process for preparing mono-carboxy-functionalized dialkylphosphinic acids, esters and salts by means of alkylene oxides and use thereof |
| abstract | The invention relates to a process for preparing mono-carboxy-functionalized dialkylphosphinic acids, dialkylphosphinic esters and dialkylphosphinic salts by means of alkylene oxides, characterized in that a) a phosphinic acid source (I) is reacted with olefins (IV) in the presence of a catalyst A to form an alkylphosphonous acid, its salt or ester (II), b) the resultant alkylphosphonous acid, its salt or ester (II) is reacted with alkylene oxides of the formula (V) in the presence of a catalyst B, to give a mono-functionalized dialkylphosphinic acid derivative (VI), und c) the resultant mono-functionalized dialkylÂphosphinic acid derivative (VI) is reacted in the presence of a catalyst C to give the mono-carboxy-functionalized dialkylphosphinic acid derivative (III), where R1, R2, R3, R4, R5, and R6 are identical or different and independently of one another are inter alia H, C1-C18-alkyl, C6-C18-aryl, C6-C18-aralkyl or C6-C18-alkylaryl, and X and Y are identical or different and independently of one another are 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 nitrogen base, and the catalysts A and C are transition metals and/or transition-metal compounds and/or catalyst systems which are composed of a transition metal and/or a transition-metal compound and at least one ligand, and the catalyst B is a Lewis acid. |
