Anion-induced migration reaction of acetylide from iron to cyclopentadienyl in (cyclopentadienyl)irondicarbonyl(acetylide) complexes

摘要

The anion-induced migration reaction of acetylide in (eta(5)-C5H5)-Fe(CO)(2)(C=CPh) 1 was observed in a sequential treatment of lithium diisopropylamide then MeI or MeC(O)Cl resulting in (eta(5)-C5H4C=CPh)Fe(CO)(2)Me 2 or (eta(5)-C5H4=Ph)Fe(CO)(2)-C(O)Me 3, respectively, the structure of 3 being confirmed by a single-crystal X-ray study.
