Abstract

The known procedures for the synthesis of 3-alkylthiophenes are rather lengthy or involved. By using the NiDPPP⁺⁺ catalyzed cross-coupling method between 3-bromothiophene and Grignard reagents derived from alkyl halides a number of 3-alkylthiophenes have been prepared in a one-step reaction in good to excellent yields.
