In the coupling reaction of 2-furyltributylstannane, 2-thienyltributylstannane, and 2-(N-methyl)pyrrolyltributylstannane (I) with 2,2,3,3-tetramethylcyclopropanecarbonyl chloride (II), cinnamoyl chloride, 1-bromo-4-nitrobenzene, and 2-chloro-3,5-dinitropyridine usual coupling products were obtained resp. in high yields except the reaction of I and II which gave 3,5-bis(2,2,3,3-tetramethylcyclopropanecarbonyl)-N-methylpyrrole. The coupling reaction of aromatic halides and heteroarylhalides with the title tin reagents took place in good yields under mild condition.
