    Abstract: A method for the formation of 3-alkylthiophenes or 3-arylthiophenes from 3-halothiophenes. More particularly, improvements on the Kumada coupling reaction for the production of 3-alkylthiophenes or 3-arylthiophenes by reacting a 3-halothiophene with an alkylmagnesiumhalide or arylmagnesiumhalide Grignard reagent in the presence of a catalyst and a 2-methyl tetrahydrofuran solvent. The 2-methyl tetrahydrofuran solvent allows for higher concentrations of the Grignard reagent with minimal or no dithienyl side product generation, achieving higher product yields and at a lower cost than other known methods.
