Abstract
Bis(propynyl)zirconocene 1 undergoes alkynyl ligand coupling upon trea tment with B(C6F5)(3); the resulting (C5H5)(2)Zr(mu-2,4-hexadiyne)BAr3 betaine 2 reacts with benzonitrile to give a Zr/B-bridging methylenec yclopropene derivative 5 that is formed via intramolecular alkyne inse rtion into a Zr-C(sp(2)) sigma bond; complex 5 was characterized by si ngle-crystal X-ray diffraction.
