Sanz Sharley, Daniel D. published the artcileAcetic acid as a catalyst for the N-acylation of amines using esters as the acyl source, Related Products of piperazines, the publication is Chemical Communications (Cambridge, United Kingdom) (2017), 53(12), 2020-2023, database is CAplus and MEDLINE.
Authors report a cheap and simple method for the acetylation of a variety of amines using catalytic acetic acid and either Et acetate or Bu acetate as the acyl source. Catalyst loadings as low as 10 mol% afforded acetamide products in excellent yields at temperatures ranging from 80-120°. The methodol. can also be successfully applied for the synthesis of a broad range of other amides, including the formation of formamides at 20°.
