In this exciting new Catalysis Science & Technology communication, Chien-Tien Chen and colleagues from Taiwan, have developed a new technique for the acetylation of alcohols using TiO2 nanoparticles functionalized with active acetate surface groups.
Acetylation of alcohols is a commonly used technique in organic synthesis, so new and better methods are constantly being sought.
Chen found that his titania based catalyst was superior to those made of ZrO2, Y2O3 and WO3 nanoparticles, and that there was no need for chromatographic purification after completion of acetylation, an advantage in practical applications.
