Based on readily available initial reagents, boron-containing compounds of various composition and structure have been synthesized. Hydroxymethyl esters of xanthogen, dithiophosphoric acids, hydroxymethylsulfamide and dialkyl esters of boric acid were used as initial reagents. As a result of the work done, a number of boron- and boron-nitrogen-containing compounds have been synthesized. The structure and composition of the synthesized compounds have been proven by studying their physicochemical properties, elemental analysis, and IR spectroscopy and gas chromatography (GLC) methods. A study of the tribological characteristics of S-(dialkyloxyboryl)xanthates and -diisopropyldithiophosphate in MS-20 aviation oil has established their high anti-seize efficiency, and the derivative of diisopropyldithiophosphoric acid is also characterized by anti-wear properties. The dependence of the extreme pressure properties of the synthesized compounds in the series of S-(dialkyloxyboryl)xanthates on the radical value in dialkyl esters of boric acid was revealed. A higher extreme pressure efficiency of the boron-containing ester of dithiphosphoric acid was shown compared to the ester of xanthic acid of a similar structure. Due to limited solubility in mineral oils, dibutoxyboryltoluenesulfamide was investigated as an antimicrobial additive in water-soluble cutting fluids (CFL). Analysis of the obtained results showed their high efficiency in this area of application.
