Oxygen Atom Transfer Reactions to Metal Carbonyls. Kinetics and Mechanism of CO Substitution of M(CO)5 (M = Fe, Ru, Os) in the Presence of (CH3)3NO
Organometallics 1989, 8, 2144-2147，-0001，（）：
Reported are rates of reaction and activation parameters for CO substitution by PPh3 of M(CO)5 (M=Fe, Ru, Os) in the presence of (CH3)3NO. The reactions follow a second-order rate law, being first-order in concentrations of M(CO)5 and of (CH3)3NO but zero-order in PPh3 concentration. The reaction rates show an approximate overall fourfold increase in the order Fe<Ru<Os. This contrasts the roughly 40-fold decrease in rate in the order Fe>Ru> Os for M3(CO)12. An attempt is made to account for the relative reaction rates of the M(CO)5 compounds and for why the order differs from that of the corresponding metal carbonyl clusters.
