A selenating reagent obtained by reacting lithium aluminum hydride with selenium powder in an organic solvent. In addition, a method for preparing a selenating reagent includes reacting lithium aluminum hydride with selenium powder in an organic solvent. Also, a method of preparing a selenium-containing product includes reacting the selenating reagent, prepared as stated, with at least one second compound which may be acyl chloride.
Various diacyl selenides, diacyl diselenides and selenocarboxylates were synthesized by reaction of several acyl chlorides with LiAlHSeH. Reaction of diacyl chloride with LiAlHSeH afforded cyclic selenoanhydrides. In the 77Se NMR spectra, we found that the chemical shifts of the diacyl selenides and the diacyl diselenides could facilitate their distinction.
