SYNTHESIS AND SPECTRAL CHARACTERIZATION OF (2E)-1-[4-(2-PHENYLIMINO- 4-SUBSTITUTEDIMINO-1,3,5-DITHIAZINO-6-YL) AMINOPHENYL]-3-(3,4-DIMETHOXYPHENYL) PROP-2-EN-1-ONE

ABSTRACT

Recently, novel series of (2E)-1-[4-(2-phenylimino-4-substitutedimino-1,3,5-dithiazino)-aminophenyl]-3-(3,4- dimethoxyphenyl)prop-2-en-1-one (IIIa-e) had been synthesized in this laboratory by refluxing (2E)-1-[4-(5-phenyl- 2,4-dithiobiureto)phenyl]-3-(3,4-dimethoxy phenyl)prop-2-en-1-one (I) with substituted alkyl/aryl isocyanodichlorides (IIa-e) in acetone medium in 1:1 molar proportion for two hours. The structures of all the synthesized compounds were justified on the basis of chemical tests, elemental analysis and spectral studies.

Keywords: alkyl/aryl isocyanodichlorides (IIa-e).
