Diacyl selenides were synthesized in good yields by the deselenization of diacyl diselenides, which have conveniently been prepared from acyl chlorides and sodium hydroselenide. The reaction of dibenzoyl selenide with piperidine at 0° C formed a fairly stable piperidinium salt. The methanolysis of distearoyl selenide gave selenostearic acid as an unstable intermediate.
