SYNTHESIS, CHARACTERIZATION, AND STRUCTURES OF α-SUBSTITUTED SELENENYL-ACETOPHENONES

A series of a-substituted selenenyl acetophenone derivatives of the types, [PhC(OCH2CH2O)CH2Se](2), [PhC(OCH2CH2O)CH2SeR], (PhCOCH2Se)(2), and [PhCOCH2 SeR] have been prepared. These compounds have been characterized by elemental analyses, IR and NMR (H-1, C-13, Se-77) spectroscopy. The compounds, [PhC(OCH2CH2)CH2Se](2) and (PhCOCH2Se)(2) have been structurally characterized by single crystal X-ray diffraction analyses. The former shows intra-molecular Se- - -O interaction, while the latter exhibits inter-molecular nonbonding Se- - -O interaction.
