Synthesis and Nmr Spectral Studies of 2e,6e-Diaroyl-3e,5e-Diaryl-1,4-Dithiane-1,1-Dioxides

Abstract

The synthesis of some 2,6-diaroyl-3,5-diaryl-1,4-dithiane-1,1-dioxides was carried out by the conjugate addition of hydrogen sulphide to 2,2′-sulphonylbis(1,3-diarylprop-2-en-1-ones) and the complete assignment of their ¹H and ¹³ C NMR chemical shifts made. The stereochemistry is found to be 2e,6e-diaroyl-3e,5e-diaryl-1,4-dithiane-1,1-dioxides from the NMR spectral data.
