Reactions of acyl chlorides with LiAlHSeH. Preparation of diacyl selenides, diacyl diselenides, selenocarboxylates and cyclic selenoanhydrides

摘要

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 Se-77 NMR spectra, we found that the chemical shifts of the diacyl selenides and the diacyl diselenides could facilitate their distinction. [References: 18]
