Title:
ビニレン類/ニトリル類を用いたモノカルボキシ官能化ジアルキルホスフィン酸、-エステル及び-塩の製造方法及びそれらの使用
Document Type and Number:
Japanese Patent JP2012507479
Kind Code:
A
Abstract:
The invention relates to a method for producing mono-carboxyfunctional zed dialkylphosphinic acids and esters and salts thereof by means of vinylenes/nitriles, 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 alkylphosphonic acid, salt or ester (II) thereof is reacted with acetylenic compounds of formula (V) to yield a mono-functionalized dialkylphosphinic acid derivative (VI) in the presence of a catalyst B, and c) the thus obtained mono-functionalized dialkylphosphinic acid derivative (VI) is reacted with a hydrogen cyanide source to yield a mono-functionalized dialkylphosphinic acid derivative (VII) in the presence of a catalyst C, and d) the thus obtained monofunctionalized dialkylphosphinic acid derivative (VII); is reacted to yield a monocarboxyfunctionalized dialkylphosphinic acid derivative (III) in the presence of a catalyst D, wherein R1, R2, R3, R4, R5, R6 are the same or different and stand independently of each other, among other things, for H, 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, B 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 the catalyst D is an acid or a base.
