| 摘要 |
The invention relates to method for producing mono amino-functionalised dialkylphosphonic 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 give an alkylphosphonous acid, the salt or ester thereof (II), b) the alkylphosphonous acid, the salt or ester thereof (II) produced above is reacted with an allylamine of formula (V) in the presence of a catalyst B to give mono amino-functionalised dialkylphosphinic acid derivatives (III) where, R1, R2, R3, R4, R5, R6, R7, R8, R9 independently=amongst others, H, C1-C18 alkyl, C6-C18 aryl, C6-C18 aralkyl, C6-C18 alkylaryl and X=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 Y=a mineral acid, a carboxylic acid, a Lewis acid or organic acid, where n=a whole or fractional number from 0 to 4, catalyst A is a transition metal and/or transition metal compound and/or catalyst system comprising a transition metal and/or a transition metal compound and at least one ligand and catalyst B is compounds forming peroxides and/or peroxide compounds and/or azo compounds. |
