Claim:
A method for producing monoallyl-functionalized dialkylphosphinic acids, esters or salts with allylic compounds, comprising the steps of a) reacting a phosphinic acid source (I) with one or more olefins (IV) in the presence of a catalyst A to form an alkylphosphonous acid, salt or ester (II) b) reacting the alkylphosphonous acid, salt or ester (II) with one or more allylic compounds of the formula (V) in the presence of a catalyst B and a base to form a monoallyl-functionalized dialkylphosphinic acid derivative (III) where R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 are identical or different and are each independently H, C 1 -C 18 -alkyl, C 6 -C 18 -aryl, C 6 -C 1 -aralkyl, C 6 -C 18 -alkylaryl, CN, CHO, OC(O)CH 2 CN, CH(OH)C 2 H 5 , CH 2 CH(OH)CH 3 , 9-anthracene, 2-pyrrolidone, (CH 2 ) m OH, (CH 2 ) m NH 2 , (CH 2 ) m NCS, (CH 2 ) m NC(S)NH 2 , (CH 2 ) m SH, (CH 2 ) m S-2-thiazoline, (CH 2 ) m SiMe 3 , C(O)R 10 , (CH 2 ) m C(O)R 10 , CH═CHR 10 or CH═CH—C(O)R 10 and where R 10 is C 1 -C 8 -alkyl or C 6 -C 18 -aryl and m is an integer from 0 to 10 and X is H, C 1 -C 18 -alkyl, C 6 -C 18 -aryl, C 6 -C 18 -aralkyl, C 6 -C 18 -alkylaryl, (CH 2 ) k OH, CH 2 —CHOH—CH 2 OH, (CH 2 ) k O(CH 2 ) k H, (CH 2 ) k —CH(OH)—(CH 2 ) k H, (CH 2 —CH 2 O) k H, (CH 2 —C[CH 3 ]HO) k H, (CH 2 —C[CH 3 ]HO) k (CH 2 —CH 2 O) k H(CH 2 —CH 2 O) k (CH 2 —C[CH 3 ]HO)H, (CH 2 —CH 2 O) k -alkyl, (CH 2 —C[CH 3 ]HO) k -alkyl, (CH 2 —C[CH 3 ]HO) k (CH 2 —CH 2 O) k -alkyl, (CH 2 —CH 2 O) k (CH 2 —C[CH 3 ]HO)O-alkyl, (CH 2 ) k —CH═CH(CH 2 ) k H, (CH 2 ) k NH 2 , (CH 2 ) k N[(CH 2 ) k H] 2 or a combination thereof, where k is an integer from 0 to 10, Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Cu, Ni, Li, Na, K, H a protonated nitrogen base or a combination thereof and Y is a halogen or acetate and the catalysts A and B are transition metals, transition metal compounds, catalyst systems composed of a transition metal, transition metal compound or combination thereof and at least one ligand or a combination thereof.
