Preparation of s 2 3 bis ethylthiomaleimidomethyl thio phosphates and s 2 3 bis ethylthiomaleimidomethyl di thio phosphates their spectral and biological properties


, : Preparation of s 2 3 bis ethylthiomaleimidomethyl thio phosphates and s 2 3 bis ethylthiomaleimidomethyl di thio phosphates their spectral and biological properties. Chemicke Zvesti 36(4): 547-558

S-[2,3-bis(ethylthio)maleimidomethyl]thio- and -dithiophosphates were prepared from N-bromomethyl-2,3-bis(ethylthio)maleimide and potassium salts of organophosphorus acids. IR, electronic and in some cases 1H-NMR spectra of the prepared compounds were measured. Linear relationship was found between v(P=O) and .SIGMA.sigma.* of the substituents on phosphorus; the effect of medium on splitting of the absorption band v(P=O) was studied. Compounds were tested for insecticidal, acaricidal, ovicidal and fungicidal activities.
