Oxygen Atom Transfer Reactions to Metal Carbonyls: Kinetics and Mechanism of CO Substitution Reactions of M₂(CO)₉L (M = Re, L = PPh₃, PMePh₂, PMe₂Ph, C₅H₅N, or M = Mn, L = C₅H₅N) in the Presence of (CH₃)₃NO

Abstract

Rates for the reactions of M₂(CO)₉L (M = Re, L = PPh₃, PMePh₂, PMe₂Ph, C₅H₅N or M = Mn, L = C₅H₅N) with L in the presence of (CH₃)₃NO as O‐atom transfer reagent and CHCl₃ as solvent are reported. The reaction rates suggest a pathway of association (k ₂). The reaction rate order of Re₂(CO)₉L with the four ligands is as follows: PPh₃ > PMePh₂ > PMe₂Ph > C₅H₅N.
