Carbonates: ecofriendly solvents for palladium-catalyzed direct 2-arylation of oxazole derivatives.
Résumé
Bien-bon-ates. Carbonates offer an environmentally friendly alternative to standard polar solvents. Since a few years, carbonates have been employed successfully for some classical metal-catalyzed reactions. Here, the palladium-catalyzed direct 2-arylation of oxazole derivatives in carbonate solvents is reported.
