The methods for the synthesis of aziridinesulfonamide derivatives by chlorine substitution in N-beta-chloroalkylsulfonamides were developed. It was found that the chlorine atom in the 3-position of aziridinesulfonamides is more reactive than that in the 4-position. It was found that the reactions of 3- and 4-chloroalkylaziridinesulfonamides with amylmercaptan in the presence of alkali lead to the replacement of the chlorine atom with the hydroxyl group along with the opening of the aziridine cycle. The reaction of 4-chloroalkylaziridinesulfonamides with 2 moles of amylmercaptan results in both chlorine substitution and aziridine cycle opening. The investigation of the synthesized compounds as additives for lubricants showed their high anticorrosive, antioxidant, and antiwear efficiency.
