Abstract

A Pd-catalyzed carbonylative multiple C-C bond formation enables an efficient route to various substituted fluoren-9-ones. The reaction proceeded smothly under a CO atmosphere, using commercially available aryl halides and arylboronic acids as substrates, in good yields with good functional-group compatibility.
