Palladium‐catalysed cyclocarbonylation reactions in dimethyl carbonate, an eco‐friendly solvent and ring‐opening reagent

Abstract
Dimethyl carbonate (DMC) is used as an alternative and eco‐friendly solvent for selective cyclocarbonylation reactions of allyl phenol derivatives for the synthesis of lactones; in some cases, depending on the reaction condition, DMC behaves as a ring‐opening reagent producing methoxycarbonyl compounds.
