Abstract
The acylation reaction of 2-butylbenzofuran with p-anisoyl chloride an d p-anisic acid in the presence of faujasite type zeolites, in the liq uid phase, is reported. A good initial selectivity to the 3-acylated d erivative is obtained, but the selectivity decreases with time. This r esult is explained by the involvement of a deacylation-reacylation pro cess.
