摘要：

The palladium-catalyzed coupling reaction between tricarbonyl(iodo-eta(5)-cyclopentadienyl)methyltungsten and various alkynyl-, aryl-, and vinylstannanes yields the corresponding coupled derivatives. The three classes of tin coupling partners were represented by (2-phenyl-1-ethynyl)trimethylstannane, 1-propynyltrimethylstannane, and 1-hexynyltri-n-butylstannane; phenyltri-n-butylstannane, and (4-methylphenyl)trimethylstannane; and (Z)-methyl 3-(tributylstannyl)acrylate, trimethylvinylstannane, and [2-(trimethylsilyl)-1(E)-ethenyl]trimethylstannane. This chemistry demonstrates a new, general route for the formation of a variety of functionally substituted eta(5)-cyclopentadienyl transition-metal compounds, whereby the cyclopentadienyl ring can be derivatized by several classes of organostannane reagents without affecting the other ligands on the transition metal.
