摘要：

The reaction of zirconacyclopentenes (1) with alkynes, nitriles, and aldehydes proceeds via cleavage of the C(beta)-C(beta') bond of 1 and displacement of ethylene by the donors to give the corresponding five-membered zirconacycles, providing a convenient means of selectively coupling alkynes with pi-donor compounds.
