-
, (2015/11/10)
The invention relates to a method for producing mono-carboxyfunctionalized dialkylphosphinic acids and esters and salts thereof, characterized in that a) a phosphinic acid source (I) is reacted with olefins (IV) to yield an alkylphosphonic acid, salt or ester (II) thereof in the presence of a catalyst A, b) the thus obtained alkyl phosphonic acid, salt, salt or ester (II) thereof is reacted with compounds of formula (V) and/or (VI′) to yield mono-functionalized dialkylphosphinic acid derivatives (VI) and/or (VI′) in the presence of a catalyst B, and c) the thus obtained mono-functionalized dialkylphosphinic acid derivatives (VI) and/or (VI′) are reacted to yield a mono-carboxyfunctionalized dialkylphosphinic acid derivative (III) in the presence of a catalyst C, wherein R1, R2, R3, R4, R5, R6, R7 are the same or different and stand independently of each other, among other things, for H1 C1-C18 alkyl, C6-C18 aryl, C6-C18 aralkyl, C6-C18 alkylaryl, and X and Y are the same or different and stand independently of each other for 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 protonized nitrogen base, and the catalysts A and C are formed by 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 formed by compounds forming peroxides and/or peroxo compounds and/or azo compounds and/or alkali metals and/or alkaline earth metals, alkali hydrides, alkaline earth hydrides and/or alkali alcoholates and alkaline earth alcoholates.

Page/Page column 13, (2008/06/13)
The invention relates to mixtures composed of dialkylphosphinic esters and of further components, which comprise A) from 98 to 100% by weight of monocarboxy-functionalized dialkylphosphinic esters of the formula (I) in which R1, R2, R3, R4, R5, R6, and R7 are identical or different and, independently of one another, are H, methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, and/or phenyl, Y is methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, phenyl, 2-hydroxyethyl, 2,3-dihydroxypropyl, 2-hydroxypropyl, 3-hydroxypropyl, 4-hydroxybutyl, 3-hydroxybutyl, 2-hydroxybutyl, and/or 6-hydroxyhexyl, allyl, and/or glycerol, X is H, Li, Na, K or NH4, or X is defined as for Y, and then X and Y are two identical radicals or two different radicals of the above organic radicals, and B) from 0 to 2% by weight of halogens, where the entirety of the components always amounts to 100% by weight.
