Abstract
Two Series of organochalcogen compounds were prepared. The first series was prepared by the reaction of 2-chloro-N-arylacetamide (where aryl is benzyl, phenyl, o-toluene, or p-toluene) with sodium hydrogen selenide (prepared in situ) to give diorganyl selenide compounds (R2Se). The second series was prepared by reaction of N-benzyl-2-chloro-N-(2-chloroacetyl)acetamide with sodium chalcogenate , Na2E (where E= S, Se, and Te) to give the corresponding cyclic chalcogenide compounds. Diiodo derivatives of cyclic selenide and telluride were also prepared. The thermal stability of the new selenium compounds (R2Se) were decomposed at 300oC. Thermogram showed a phase transfer point between 120-150oC indicating that these compounds may act as liquid crystal compounds. All new compounds were characterized by CHN elemental analysis, UV-Visible, FT-IR and 1H NMR spectroscopic data.
