WebLithiation followed by formylation of the resulting organolithium compounds changes this ratio to 20 : 80. The formylation of methyl thieno [3,4- b ]thiophene-2-carboxylate has been shown to give the 4- and 6-substituted isomers in a 50 : 50 ratio. WebMethods for the large-scale synthesis of thieno[3,2-b]thiophene [including a catalytic vapour-phase reaction (at 550 °C) between 2-(2-thienyl)ethanol and carbon disulfide], its 2-carboxylic acid and its 3,6-dibromo and 2,3,5,6-tetrabromo derivatives are reported.
