A general, versatile method for alkylation and arylation of haloheterocyclic compounds is reported.In the presence of a catalytic quantity of , where dppp stands for Ph2P(CH2)3PPh2, bromothiophenes, halopyridines, haloquinoline, and haloisoquinolines reacted with alkyl and aryl Grignard reagents at room temperature or at ether refluxing temperature to give the cross-coupling products.The coupling reactions has been applied to the synthesis of isoquinoline alkaloids.Reactivities of 2-thienyl and 2-pyridyl Grignard reagents have also been examined.

A lignan skeleton is prepared in good yield through desulfurization of 3,4-dibenzylthiophene or 2,5-diaryl-3,4-dimethylthiophenes which are obtained by nickel- or palladium-phosphine complex catalyzed Gringard cross-coupling reaction of halothiophenes.
