✦ Synopsis
Reactions of Thioaroylketene S,N-Acetals with 1,3-Dicarbonyl Compounds in the Presence of Mercury(II) Acetate: A General Route to 2-Acyl-and2-Aroyl-3-(alkylamino)-5-arylthiophenes and2-(Ethoxycarbonyl)-3-(methylamino)-5-arylthiophenes. -A wide variety of active methylene compounds such as 1,3-diketones, acetoacetate, and β-sulfinyl and β-sulfonyl esters can be used for the synthesis of the title compounds in moderate to high yields. The reactions do not occur in the absence of mercury(II) acetate. -(KIM, B.
