Recently reported reactions of group 4 metallocene bis(trimethylsilyl)acetylene complexes from the last two years are summarized. This could be considered as a never-ending story. A recently reported alternative and very straightforward method for the preparation of the well-known alkyne complex Cp₂Ti(η²-Me₃SiC₂SiMe₃) reported by Beckhaus et al. could in the future have a great effect on the application of this complex. Similar improvements made earlier by Tilley and co-workers for the Zr analogue Cp₂Zr(py)(Me₃SiC₂SiMe₃) have enabled preparative organometallic and organic chemists to establish this reagent for a wide range of coupling reactions. Examples of this are summarized in this review. These and similar reagents represent excellent sources to yield the very reactive coordinatively and electronically unsaturated complex fragments [Cp′₂M]. They will have a great potential for a large number of interesting applications in the future.

第4组茂金属双（三甲基硅烷基）乙炔配合物的反应更新：一个永无止境的故事吗？

总结了最近两年最近报道的第4组茂金属双（三甲基甲硅烷基）乙炔配合物的反应。这可以被认为是一个永无止境的故事。最近报道的替代的和非常简单的方法为公知的炔复杂Cp的制备₂的Ti（η ² -Me ₃的SiC ₂森达₃）报道Beckhaus等。将来可能会对这种复合物的应用产生巨大影响。Tilley及其同事先前对Zr模拟Cp ₂ Zr（py）（Me ₃ SiC ₂ SiMe ₃）使制备有机金属和有机化学家能够建立用于广泛偶联反应的试剂。这篇综述总结了这样的例子。这些和类似的试剂代表优良来源，以产生反应性非常高的配位且电子不饱和复杂片段[CP' ₂ M]。将来，它们将在大量有趣的应用程序中具有巨大的潜力。
