Abstract

20 21 anhydride (100" for 24 hr). Similarily, phenyl p-tolyl sulfoxide and phenyl o-tolyl sulfoxide were recovered, essentially quantitatively, even when benzoic anhydride at 187" was used in place of hot acetic anhydride. Failure of vinyl sulfoxides to undergo the Pummerer reaction with acetic anhydride is consistent with the conclusion that elimination of acetic acid from 1 occurs by a cyclic elimination mechanism'" in 22. The possibility cannot, ...
