Carbonyl compounds were added to selenocarbamoyllithiums to generate α-hydroxy and α-oxo selenoamides. Their conformations were determined by X-ray analyses. These compounds adopted conformations that were almost identical to those of ordinary amides. Unlike the consistency of the chemical shifts of the C═Se groups of the selenoamides in (13)C NMR spectra and the (1)J coupling constants of the C═Se groups, the substituents far from the selenium atom influenced the chemical shifts in (77)Se NMR.
