Boron chelate complexes

摘要

Boron chelate complexes of the general formula are described, where X is either -C(R¹R²)- or -C(R¹R²)-C(-O)-, in which R¹, R² independently of one another denote H, alkyl (with 1 to 5 C atoms), aryl, silyl or a polymer, and one of the alkyl radicals R¹ or R² 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 in which S¹, S² independently of one another denote alkyl (with 1 to 5 C atoms), fluorine or a polymer, as well as M⁺ denotes Li⁺, Na⁺, K⁺, Rb⁺, Cs⁺ or [(R³R⁴R⁵R⁶)N]⁺ or H⁺, where R³, R⁴, R⁵, R⁶ independently of one another denote H or alkyl with preferably 1 to 4 C atoms.
