| titleOfInvention | Improved process for the kumada coupling reaction |
| 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-hâlothiophene 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. |
