The invention relates to a method for producing monofunctionalized dialkylphosphinic acids, esters, and salts, characterized in that 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 thereof, whereupon said alkylphosphonous acid, the salt or ester (II) thereof is reacted with compounds containing C═C, C═O, or C═N double bonds to obtain compounds of type (III), wherein R1, R2, R3, R4, R5, R6 are identical or different from each other and independently represent, inter alia, H, C1-C18-alkyl, C6-C18-aryl, C6-C18-aralkyl, X represents, inter alia, H, C1-C18-alkyl, C6-C18-aryl, and/or Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Cu, Ni, Li, Na, K, H, and wherein A represents OH, NH2, NHR, NR2, or O—CO—R8, and W represents a mineral acid, carboxylic acid, Lewis acid, or organic acid, wherein n is a whole or a fractional number from 0 to 4, and 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. The use of said dialkylphosphonic acids, esters, and salts is also disclosed.
该发明涉及一种生产单官能化二烷基膦酸、酯和盐的方法,其特征在于将膦酸源(I)与烯烃(IV)在催化剂A的存在下反应,以获得烷基膦酸、其盐或酯,然后将所述烷基膦酸、其盐或酯(II)与含有C═C、C═O或C═N双键的化合物反应,以获得类型(III)的化合物,其中R1、R2、R3、R4、R5、R6相互独立地且相同或不同地代表H、C1-C18-烷基、C6-C18-芳基、C6-C18-芳基烷基等,X代表H、C1-C18-烷基、C6-C18-芳基和/或Mg、Ca、Al、Sb、Sn、Ge、Ti、Fe、Zr、Zn、Ce、Bi、Sr、Mn、Cu、Ni、Li、Na、K、H等,A代表OH、NH2、NHR、NR2或O—CO—R8,W代表矿酸、羧酸、Lewis酸或有机酸,n是从0到4的整数或分数,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个配体组成的催化剂系统。还揭示了所述二烷基膦酸、酯和盐的用途。
