Abstract:
A process for preparing a difluoro chelato borate salt comprising an anion A of formula (I) wherein is a bidentate radical derived from a 1,2-, 1,3- or 1,4-diol, from a 1,2-, 1,3- or 1,4-dicarboxylic acid or from a 1,2-, 1,3- or 1,4-hydroxycarboxylic acid by abstracting the two H atoms of pairs of adjacent OH groups of the respective diol, hydroxycarboxylic acid or dicarboxylic acid. The process includes step (i) reacting (a) one or more BF3 sources; (b) a dihydric compound selected from 1,2-, 1,3- and 1,4-diols, 1,2-, 1,3- and 1,4-dicarboxylic acids, and 1,2-, 1,3- and 1,4-hydroxycarboxylic acids; (c) one or more second boron sources which do not contain F; and (d) one or more proton acceptors.

Claim (Index 11):
The process according to  claim 1 , wherein the proton acceptor (d) is selected from organic amines NR 1 R 2 R 3 , NH 4 OH, and organic ammonium hydroxides [NR 1 R 2 R 3 R 4 ]OH\n wherein R 1 , R 2 , R 3 , and R 4  are selected independently from each other from H, optionally substituted C 1 -C 20  alkyl, C 2 -C 20  alkenyl, C 2 -C 20  alkynyl, C 5 -C 12  (hetero)aryl, and C 6 -C 30  (hetero)aralkyl, wherein one or more CH 2  groups of alkyl, alkenyl, alkynyl and (hetero)aralkyl which are not directly bound to the N-atom may be replaced by O, 1,2-epoxyethylene, cyclopropylene, OSO 2 , SO 2 O, OC(O), C(O)O, OC(O)O, or OC(O)C(O)O; or wherein R 1  and R 2  are linked and jointly selected from a 4- to 5-membered hydrocarbon group forming together with the central N-atom a five- or six-membered heterocycle which may substituted by one or more substituents selected from C 1 -C 10  alkyl, and wherein one or more members of the 4- to 5-membered hydrocarbon group may be replaced by one or more O, S or NR\u2032; R\u2032 is selected from H, C 1 -C 10  alkyl, C 2 -C 10  alkenyl, C 2 -C 10  alkynyl, C 6 -C 12  aryl, and C 7 -C 24  aralkyl, which may be substituted by one or more groups selected from F, cyclopropyl, 1,2-epoxyethyl, and sulfonate, and wherein one or more CH 2  groups of alkyl, alkenyl, alkynyl and aralkyl which are not directly bound to the N-atom may be replaced by O, 1,2-epoxyethylene, cyclopropylene, OSO 2  or SO 2 O; and wherein at least one of R 1 , R 2 , and R 3  is not H.
