摘要

摘要报道了M2(CO)9L (M = Re, L = PPh3, PMePh2, PMe2Ph, C5H5N或M = Mn, L = C5H5N)与L在(CH3)3NO为O原子转移试剂，CHCl3为溶剂下的反应速率。Re2(CO)9L与四种配体的反应速率顺序为:PPh3 > PMePh2 > PMe2Ph > C5H5N。

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.
