Boron chelate complexes of the general formula n n n n n n n n n n are described, where n X is either —C(R 1 R 2 )— or —C(R 1 R 2 )—C(═O)—, in whichn R 1 , R 2 independently of one another denote H, alkyl (with 1 to 5 C atoms), aryl, silyl or a polymer, and one of the alkyl radicals R 1 or R 2 may be bonded to a further chelatoborate radical, or X denotes 1,2-aryl with up to two substituents S in the positions 3 to 6 nn n n n n n n n n n in which S 1 , S 2 independently of one another denote alkyl (with 1 to 5 C atoms), fluorine or a polymer,n as well as M + denotes Li + , Na + , K + , Rb + , Cs + or [(R 3 R 4 R 5 R 6 )N] + or H + , where R 3 , R 4 , R 5 , R 6 independently of one another denote H or alkyl with preferably 1 to 4 C atoms. |
