Abstract: S-[l-Acetyl-2-(2-oxobenzothiazol-3-yl)ethyl] 0,0(0,N,0,S)-dialkyl thio-(dithio)phosphates have been prepared by treatment of 3-(2-bromo-3-oxobutyl)-2-benzothiazolinone with salts of 0,0(0,М,0,S)-dialkyl thio-(dithio)phosphoric acids and S-[l-acetyl-2-(2-thioxobenzothiazol-3-yl)-ethyl] 0,0(0,N)-dialkyl thio(dithio)phosphates by treatment of 2,3-dihydro-2-acetylthiazolo[2,3-b]benzothiazolium bromide with salts of 0,0(0,N)-dialkyl thio(dithio)phosphoric acids. The structures of the prepared com­ pounds were proved by their ¹H NMR and IR spectra. It has been found that bromination of 3-(3-oxobutyl)-2- benzothiazolinethione resulted in 2,3-dihydro-2-acetylthiazolo[2,3-b]benzothiazolium bromide. The compounds at lower concentrations did not exhibit sufficiently high pesticidal activity.
