Abstract: Sixteen S-[2,3-bis(ethylthio)maleimidomethyl] thio- and -dithiophosphates I (R = alkyl; R1 = alkoxy, Ph, Me₂N; Z = O, S) were prepd. from N-(bromomethyl)-2,3-bis(ethylthio)maleimide and K salts of organophosphorus acids. IR, UV and ¹H NMR spectra were measured. A linear relationship was found between ν(P = O) and Σσ* of the P substituents; the effect of the medium on the splitting of the absorption band ν(P = O) was studied. The prepd. compds. were tested for insecticidal, acaricidal, ovicidal, and fungicidal activities.
