Claim Text:
1. A method for producing monofunctionalized dialkylphosphinic acids, esters or salts comprising the steps of: a) reacting a phosphinic acid source (I) with olefins (IV) in the presence of at least one catalyst A to form an alkylphosphonous acid, salt or ester (II) b) reacting the alkylphosphonous acid, salt or ester (II) with one or more compounds C═C, C═O or C═N, wherein compounds C═O are ketones of the type R 5 R 6 C═O or aldehydes of the type R 5 CHO, wherein compounds C═C are selected from the group consisting of vinyl acetate, vinyl propionate, vinyl butyrate, vinyl pivalate, vinyl benzoate, vinyl cinnamate, vinyl stearate, vinyl laurate, 1-propenyl acetate, 1-propenyl propionate, 1-propenyl butyrate, 1-propenyl pivalate, 1-propenyl benzoate, 1-propenyl cinnamate, 1-propenyl stearate, 1-propenyl laurate, 1-butenyl acetate, 1-butenyl propionate, 1-butenyl butyrate, 1-butenyl pivalate, 1-butenyl benzoate, 1-butenyl cinnamate, 1-butenyl stearate and 1-butenyl laurate to form a compound (III) where R 1 , R 2 , R 3 , R 4 , R 5 , R 6 are identical or different and are H, methyl, ethyl, n propyl, isopropyl, n-butyl, isobutyl, tert-butyl, phenyl 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 SH, (CH 2 ) m S-2-thiazoline, (CH 2 ) m SiMe 3 , CHR 7 (CH 2 ) m CH 3 , C(O)R 7 , (CH 2 ) m C(O)R 7 , CH═CHR 7 , R 5 R 6 C═CHR 7 , CH═CH—C(O)R 7 , wherein R 7 is H, C 1 -C 8 -alkyl or C 6 -C 18 -aryl, m is an integer from 0 to 10 and X is H, n-butyl, isobutyl, tert-butyl, phenyl, ethylene glycol, propyl glycol, butyl glycol, pentyl glycol, hexyl glycol, allyl, glycerol (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 —CH 2 O) k -alkyl, (CH 2 —C[CH 3 ]HO) 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 or (CH 2 ) k N[(CH 2 ) k H] 2 , wherein 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 wherein A is OH, NH 2 , NHEt, NHCH(C 6 H 5 ) 2 or O—CO—R 8 and R 8 has the same meanings as R 1 to R 6 and W is hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, phosphonic acid, phosphinic acid, formic acid, acetic acid, propionic acid, butyric acid, lactic acid, palmitic acid, stearic acid, malonic acid, maleic acid, fumaric acid, tartaric acid, citric acid, ascorbic acid, trimethylborane, triethylborane, tributylborane or triphenylborane, where n is an integer or fraction ranging from 0 to 4 and the at least one catalyst A is a transition metal, transition metal compound, a catalyst system including a transition metal, transition metal compound and at least one ligand or a combination thereof.
