Sunlamp-Irradiated Phase-Transfer Catalysis. 1. Cobalt Carbonyl Catalyzed SRN1 Carbonylations of Aryl and Vinyl Halides

Article abstract of DOI:10.1021/jo00156a004

Cobalt carbonyl catalyzed carbonylation (1 atm) of aryl and vinyl halides may be easily achieved under phase-transfer-catalysis conditions provided that the reaction medium is irradiated.Irradiation may be achieved by a commercial sunlamp.Most of these reactions may also be performed without organic solvent and in some cases without a phase-transfer agent.Finally, this new, inexpensive carbonylation method allows very efficient synthesis of benzolactams and benzolactones.
