- 中文摘要: Syntheses of 2,5-bis(4-methyl-2-thienyl)thiophene and 2,5-bis(4-methyl-2-thienyl)pyrrole are described. The key step involves Stetter reaction between 4-methyl-2- thiophenecarboxaldehyde and divinyl sulfone. Cyclizaton of the resulting 1,4-bis-(4- methyl-2-thienyl)-1,4-butanedione with Lawesson's reagent gives 2,5-bis(4-methyl-2-thienyl) thiophene, whereas condensation with ammonium acetate provides the 2,5-bis(4-methyl-2-thienyl)pyrrole.
