ABSTRACT
A series of new selenium-containing heteroatom compounds were synthesized in good yields by the reaction of Woollins’ reagent with various organic substrates such as cyclohexylamine, N-benzoylbenzamide, benzoic anhydride, 4-fluoro-N-(2-oxo-2-phenylethyl)benzamide, N-benzoylbenzamide, benzoic anhydride, 3-(bromomethyl)benzonitrile, 1,2-diphenylethane-1,2-diol, and sodium alcoholate. Three representative X-ray structures are described.
