Abstract
The catalytic system involving Sc (OTf) 3 and a dendritic terpyridine ligand is able to promote the Friedel–Crafts acylation of a wide range of aromatics under microwave irradiation. The expected products are obtained in high yields after short reaction times and the nano-sized catalyst can be recovered and successfully used in 12 consecutive runs.
