COMPLEXES OF GADOLINIUM WITH 4-DIHYDROXYBOROPHENYLAMINE Russian patent published in 2010 - IPC C07F5/00 C07F5/02 

FIELD: chemistry.

SUBSTANCE: invention relates to chelate complexes of gadolinium (III). Complexes of Gd³⁺ with 4-dihydroxyborophenylamine (DHBPA) have formula Gd(DHBPA)₃, and complexes of Gd³⁺ with DHBPA and monosaccharide (M), which is in the inner sphere of the complex, have formula: M₃[Gd(DHBPA)₃]. DHBPA molecules enter the coordination sphere of gadolinium through nitrogen and oxygen atoms of the alanine fragment. Monosaccharides, e.g. fructose and/or ribose, form outer-sphere complexes on hydroxyl groups of borophenyl in DHBPA, built in the inner coordination sphere of Gd³⁺.

EFFECT: obtaining new compounds.
