Anion-induced migration reaction of acetylide from iron to cyclopentadienyl in (cyclopentadienyl)irondicarbonyl(acetylide) complexes
Abstract
The anion-induced migration reaction of acetylide in (η5-C5H5)Fe(CO)2(CCPh) 1 was observed in a sequential treatment of lithium diisopropylamide then MeI or MeC(O)Cl resulting in (η5-C5H4CCPh)Fe(CO)2Me 2 or (η5-C5H4CCPh)Fe(CO)2C(O)Me 3, respectively, the structure of 3 being confirmed by a single-crystal X-ray study.
