Mariella, R. P. published the artcileNovel SNl displacement. Reaction of tertiary amines with acetic anhydride, Computed Properties of 101-98-4, the publication is Canadian Journal of Chemistry (1971), 49(20), 3348-51, database is CAplus.
The action of Ac2O on tertiary amines at reflux may cause the displacement of one of the R groups from the amine. The groups which are displaced are benzyl, tert-Bu, benzhydryl, trityl, and cinnamyl; the groups which are not displaced are Me, Et, Bu, Ph, α-naphthyl, iso-Pr, allyl, and propargyl, An SN 1 mechanism with special steric requirements is consistent with the results.
