ne. In contrast, zirconocene–alkyne complexes, such as those of 1-(trimethylsilyl)prop-1-yne and diphenylacetylene, gave 1-zirconacyclohept-2-en-5-yne in good yields. Consideration of structural parameters suggests that both a seven-membered cyclic alkyne and a five-membered structure contribute to generation of this complex. Coupling of benzyne and [3]cumulenes on a metal was also found to afford
合成了七元金属环炔化合物。锆茂-乙烯配合物和 (Z)-1,4-双(三甲基甲硅烷基)buta-1,2,3-triene 的反应得到 1-zirconacyclopent-3-yne 和 1-zirconacyclohept-3-yne 的混合物。相比之下,锆茂 - 炔烃配合物,例如 1-(三甲基甲硅烷基)prop-1-yne 和二苯乙炔的配合物,以良好的产率得到 1-zirconacyclohept-2-en-5-yne。考虑结构参数表明,七元环炔烃和五元结构都有助于生成这种复合物。还发现苯和 [3] 枯烯在金属上的偶联可提供相应的金属环。
