| abstract |
The invention relates to boron chelate complexes of general formula (I): in which either X represents -C(R1R2)- or -C(R1R2)-C(=O)-, whereby R1 and R2, independent of one another, represent H, alkyl (with 1 to 5 C atoms), aryl, silyl or polymer, and one of the alkyl radicals R1 or R2 can be bound to another chelatoborate radical or X represents 1,2-aryl with up to 2 substituents S in positions 3 to 6 (II), whereby S1 and S2, independent of one another, represent alkyl (with 1 to 5 C atoms), fluorine or polymer, and M+ represents Li+, Na+, K+, Rb+, Cs+ or [(R3R4R5R6)N]+ or H+, in which R3,R4,R5,R6, independent of one another, represent H or alkyl with preferably 1 to 4 C atoms. |
