Ionic-liquid-promoted palladium-catalyzed multicomponent cyclocarbonylation of o-iodoanilines and allenes to form methylene-2,3-dihydro-1H-quinolin-4-ones.


PMID 17408285

Abstract

The palladium-catalyzed cyclocarbonylation reaction of o-iodoanilines with allenes and CO in 1-butyl-3-methylimidazolium hexafluorophosphate afforded 3-methylene-2,3-dihydro-1H-quinolin-4-ones in moderate to excellent yields under a low pressure (5 atm) of CO. The ionic liquid, as the solvent and promoter, enhances the efficiency of the cyclocarbonylation reaction. The recyclability of the system of ionic liquid/catalyst/ligand was also demonstrated.
