The invention relates to a process for preparing mono-allyl-functionalized dialkylphosphinic acids, esters and salts with allylic compounds, characterized in that a) a phosphinic acid source (I) is reacted with olefins (IV) in the presence of a catalyst A to give an alkylphosphonous acid, or salt or ester thereof (II), b) the alkylphosphonous acid, or salt or ester thereof (II) thus formed is reacted with allylic compounds of the formula (V) in the presence of a catalyst B and of a base to give a mono-allyl-functionalized dialkylphosphinic acid derivative (III), where R1, R2, R3, R4, R5, R6, R7, R8, R9 are the same or different and are each independently, inter alia, H, C1-C18-alkyl, C6-C18-aryl, C6-C18-aralkyl, C6-C18-alkylaryl, and X is 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 B 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.
该发明涉及一种制备单烯基功能化二烷基膦酸、酯和盐的过程,其中利用烯基化合物与膦酸源(I)在催化剂A的存在下反应,得到烷基膦酸、盐或酯(II),然后将得到的烷基膦酸、盐或酯(II)与化合物(V)在催化剂B和碱的存在下反应,得到单烯基功能化的二烷基膦酸衍生物(III)。其中R1、R2、R3、R4、R5、R6、R7、R8、R9可以相同也可以不同,分别独立地为H、C1-C18-烷基、C6-C18-芳基、C6-C18-芳基烷基、C6-C18-烷基芳基,X为H、C1-C18-烷基、C6-C18-芳基、C6-C18-芳基烷基、C6-C18-烷基芳基、Mg、Ca、Al、Sb、Sn、Ge、Ti、Fe、Zr、Zn、Ce、Bi、Sr、Mn、Cu、Ni、Li、Na、K和/或质子化的氮碱基。而催化剂A和B为过渡金属和/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。
