Popis:	The iron acetylide Cp*(dppe)FeC⋮CH (Cp* = η5-C5Me5, dppe = Ph2PCH2CH2PPh2) reacted with [Cp2Zr(H)Cl]n (Schwartz's reagent, Cp = η5-C5H5) to produce the C⋮C-bridged complex Cp*(dppe)FeC⋮CZrClCp2 in nearly quantitative yield instead of the expected CHCH-bridged hydrozirconation product. The bulky ligand set around iron is postulated to prevent the addition of hydride at the carbon α to the metal center. Reaction of Cp*(dppe)FeC⋮CH with (dimethylamino)trimethyltin gave the condensed product Cp*(dppe)FeC⋮CSnMe3 in nearly quantitative yield.
