P. Amouzegh et al., ACYLATION OF A SUBSTITUTED BENZOFURAN OVER AN HY ZEOLITE AND ITS SUBSEQUENT DEACYLATION AND REACYLATION, Catalysis letters, 34(3-4), 1995, pp. 389-394
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.
