FIELD: chemistry.
SUBSTANCE: invention relates to the technology of producing organoboron compounds, particularly a method of producing C,C'-carborane dicarboxylic acids by oxidising 1,2-bis(hydroxymethyl)-o-, 1,7-bis(hydroxymethyl)-m- and 1,12-bis(hydroxymethyl)-p-carboranes and separating the end product. Oxidation is carried out with halochromates or bichromates of nitrous heterocyclic bases at 20-30°C for 3-8 hours. The process is carried out in a medium of organic amide solvents in the form of N,N-dimethyl formamide, N,N-dimethyl acetamide, N-methylpyrrolidone, 1,3-dimethyl-2-imidazolidinone, 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone.
EFFECT: invention simplifies the method of producing C,C'-carborane dicarboxylic acids.
