Under anhyd. conditions, olefins (ethene, isobutene, and 1-octene) react (within the zeolite) with CO on HZSM-5 at 296 K to give unsatd. ketones and stable 5-membered carboxonium ions. The first evidence was obtained for the Friedel-Crafts acylation of alkenes in zeolite catalysts at ambient temps. by acylium cations, generated in situ from CO and alkenes.
