Abstract
The iron acetylide Cp*(dppe)FeC≡CH (Cp* = η5-C5Me5, dppe = Ph2PCH 2CH2PPh2) reacted with [Cp2Zr(H)Cl] n (Schwartz's reagent, Cp = η5-C5H 5) to produce the C≡C-bridged complex Cp*(dppe)Fe- C≡CZrClCp2 in nearly quantitative yield instead of the expected CH=CH-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)Fe-C≡CSnMe 3 in nearly quantitative yield.
