Abstract: Cute CO! An interesting and straightforward procedure for the carbonylative synthesis of chromenones from readily available salicylic aldehydes and benzyl chlorides has been developed (see scheme; DPPP = 1,3-bis(diphenylphosphino)propane). In the presence of a palladium catalyst, various coumarins were produced in good to excellent yields.<br /> (Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.)
