摘要：

The acylation reaction of 2-butylbenzofuran with p-anisoyl chloride and p-anisic acid in the presence of faujasite type zeolites, in the liquid phase, is reported. A good initial selectivity to the 3-acylated derivative is obtained, but the selectivity decreases with time. This result is explained by the involvement of a deacylation-reacylation process.
