acyldemetallation reactions of organomercurials (R2Hg or AlkHgI) provide a mild, selective, and general method for the synthesis of unsymmetrical heterocyclic ketones. High yields of ketones (RCOR′) were obtained along with small amounts of homocoupling products (R2). The reaction is accelerated by a nucleophilic catalyst with both organic groups of R2Hg taking part in the reaction. The selectivity
respectively. The thermal decompositions of these compounds, together with that of 2,2'-dithienyl mercury, have been studied. The 2-thiophenemercuric triflate (6) decomposes at room temperature to give 2,2'-dithienylmercury. The 2-azide (4), when treated with either cyclohexene or triphenylphosphine, gave only the 2,2'-dithienylmercury. All the 2-thiophenemercuric salts decompose at about 300°C to give
