Popis: The dissociative displacement of the THF solvent molecule from LRe(CO)2−THF (L = Tp, Tp*, Cp*) and of MenTHF (n = 1, 2) from TpRe(CO)2−MenTHF by acetonitrile is studied. While the reactivity of the Re−THF bond depends on the electronic properties of the ancillary ligands (Tp, Tp*, Cp*) attached to the metal center, the lability of the Re−MenTHF bond is primarily influenced by the steric demands of the departing solvent.
