Patent

CA 2438611

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.

L'invention concerne des complexes de chélate de bore de formule générale (I) dans laquelle soit X = -C(R?1¿R?2¿)- ou C(R?1¿R?2¿)C(=O)-, R?1¿, R?2¿ désignant indépendamment l'un de l'autre H, alkyle (ayant entre 1 et 5 atomes de C), aryle, silyle ou polymère, et un des restes alkyle R?1¿ ou R?2¿ peut être lié à un autre reste chélatoborate, soit X = 1,2-aryle, ayant jusqu'à 2 substituants S dans les positions 3 à 6, S?1¿, S?2¿ désignant indépendamment l'un de l'autre alkyle (ayant entre 1 et 5 atomes de C), fluor ou polymère, ainsi que M?+¿ = Li?+¿, Na?+¿, K?+¿, Rb?+¿, Cs?+¿ ou [(R?3¿R?4¿R?5¿R?6¿)N]?+¿ ou H?+¿, R?3¿, R?4¿, R?5¿, R?6¿ désignant indépendamment les uns des autres H ou alkyle ayant de préférence entre 1 et 4 atomes de C.
