The acylation of anisole, phenetole or diphenyl ether with carboxylic
anhydrides at 100 degrees C in the presence of catalytic quantities of
zeolite H-beta gives the corresponding para-acylated products in high
yield; the zeolite can be recovered, regenerated and reused to give a
lmost the same yield as that given by fresh zeolite. (C) 1998 Elsevier
