Abstract: Solvent-free acetylation of alcohols phenols

Supplementary Material. The object of the present experiment is to synthesize an aromatic amide by addition-elimination reaction with acetic anhydride.
Under the conditions of our experiments there is no indication of the formation of any acetic anhydride and the acetylation seems to have been effected by the
such as phenols and aromatic amines preferentially occurs at the substituent The acylation of anisole with acetic anhydride is carried out in a flow.
