assigned Cu(CO)3+, Ag(CO)+ instead of the previously assigned Ag(CO)2+, and Au(CO)2+, respectively, for the copper(I), silver(I) and gold(I) carbonyl cation-catalyzed carbonylation of olefins and alcohols in concentrated sulfuric acid. The reaction mechanism previously proposed for the metal carbonyl cation-catalyzed carbonylation has been modified to involve an olefin-metal-monocarbonyl (e.g., for Ag)
