Abstract :
N-Methyl-2-phenylimidazole (Ph-NMI) and 2-phenylimidazo[2,1-b]benzothiazoles (Ph-IBT) catalyzed selective acylation of primary alcohols using acid anhydrides. The Ph-NMI- or Ph-IBT-catalyzed reaction using (PhCO)2O as an acylating agent could particularly acylate the primary hydroxy group of 1,n-diols (n ⩾ 3) with a high, synthetically useful selectivity.
