Adventitious formation of a new oxopentadienyl Mn(I) tricarbonyl complex

Résumé

A Mn(I) tricarbonyl complex of a 1,3-diferrocenyl-1-oxopentadienyl ligand was synthesized adventitiously by what seems to be an in-situ aldol-like condensation of two acetylferrocene units promoted by benzyl-Mn(CO)5. X-ray structural anal. of this unexpected product confirms the η5 coordination of the 1,3-diferrocenyl-1-oxopentadienyl ligand to the Mn(CO)3 moiety. The nature of the metal-ligand bonding relationship was studied by theor. calcns.; it outlines the charge unbalance (polarization) at the oxopentadienyl moiety as well as the lack of ketone character of the latter Mn-bound ligand.
