A method for producing monohydroxy-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, b) the obtained alkylphosphonous acid, the salt or ester (II) thereof is reacted with alkylene oxides of formula (V) in the presence of a catalyst B to obtain a monofunctionalized dialkylphosphinic acid derivative (III), 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 is a Lewis acid.
一种生产单羟基功能化二烷基膦酸、酯和盐的方法,其特征在于a) 在催化剂A的存在下,将膦酸源(I)与烯烃(IV)反应,以获得烷基膦酸、其盐或酯(II),b) 在催化剂B的存在下,将获得的烷基膦酸、其盐或酯(II)与化学式(V)的烷基氧化物反应,以获得单功能化的二烷基膦酸衍生物(III),催化剂A代表过渡金属和/或过渡金属化合物和/或由过渡金属和/或过渡金属化合物以及至少一种配体组成的催化剂系统,而催化剂B是一种路易斯酸。
