Polymer‐supported bases. 5. Acetylation of linalool with acetic anhydride using dialkylaminopyridines attached by spacer chains to polystyrene resins

The acetylation of linalool with acetic anhydride was carried out in the presence of polystyrene‐bound aminopyridines and triethylamine. The catalytic activity of the immobilized aminopyridines increased with decreasing percentage of ring substitution and with increasing spacer‐chain length. The increased activity is attributed to an increase in the amount of aminopyridine units complexed with acetic anhydride. The acetylation could be successfully conducted by use of a mixture of the immobilized aminopyridines and polymer‐supported benzyldiethylamine, which effectively trapped acetic acid formed in the reaction system.
