Photochemical reactions between dinuclear metal carbonyl complexes and alkyl halides. Formal oxidative addition across a metal-metal single bond proceeding by a free radical chain mechanism

Photochemical reactions between (L = CO, PBu3, PEt3, P(OMe)3, P(OPh)3, PPh3) and alkyl halides (RX) yield both alkyl and halo complexes, and , in equimolar quantities.Kinetic and quantum yield studies suggest that these reactions proceed by a radical chain pathway involving CO dissociation from the dinuclear complex and metal-metal bond homolysis of the coordinatively unsaturated dinuclear intermediate.

Thermal reactions between and alkyl halides; evidence for an outer-sphere electron transfer process

Thermal reactions between 2(CO)8(PBu3)2> and some alkyl halides (RX) yield both 4PBu3> and 4PBu3>.Kinetic and other studies suggest that the reactio

Low-temperature photochemistry of (η5-C5H5)Mo(CO)3Mn(CO) 5: Identification of an unexpectedly stable coordinatively unsaturated heterodinuclear carbonyl complex

The low-temperature photochemistry of (η5-C5H5)Mo(CO)3Mn(CO) 5 has been investigated in rigid methylcyclohexane at 93 K. Irradiation at either 313 or 366 nm results in loss of CO as the only photoreaction, and the relative efficiency of CO loss in the glass was established as Φ313/Φ366 ≈ 15, with Φdiss = 10-3 at 313 nm. The origin of photoejected CO (Mo or Mn) cannot be established by a selective 13CO labeling of the starting complex because 13C NMR shows rapid scrambling of CO at 298 K. IR and UV-vis measurements made after the glass was warmed and cooled establish that two isomers of the CO loss product exist, and the more unstable isomer undergoes rapid thermal conversion to the more stable isomer upon melting the glass. No significant wavelength dependence on the product distribution is observed, indicating that both isomers are formed from the decay of the same excited state. The structure of the more stable isomer of (η5-C5H5)MoMn(CO)7 features six terminal CO ligands and one bridging CO as deduced from the IR spectrum and is assigned a structure featuring a bridging CO, (η5-C5H5)Mo(CO) 2(μ-CO)Mn(CO)4. The less stable isomer of (η5-C5H5)MoMn(CO)7 is formulated as having a μ-η1, η2-CO. Both isomers react with CO in fluid methylcyclohexane to yield (η5-C5H5)Mo(CO)3Mn(CO) 5. At 298 K (η5-C5H5)MoMn(CO)7 reacts with CO to quantitatively yield (η5-C5H5)Mo(CO)3Mn(CO) 5 with a rate constant of 1.4 × 102 M-1 s-1. Kinetic measurements were made to determine the activation parameters (ΔH? = 24.0 ± 2 kJ mol-1 and ΔS? = -140 ± 20 J mol-1 K-1) for the reaction of the more stable isomer of (η5-C5H5)MoMn(CO)7 with CO, and the results indicate that the rate is controlled by a large entropic contribution.

Reactions between Dinuclear Metal Carbonyl Complexes and Alkyl Halides: Formal Oxidative Addition across a Metal-Metal Single Bond

Photochemical reactions between 2> (R=Et, Bun, OEt) and alkyl halides (R'X) proceed to completion in 2 to 4 h yielding equimolar quantities of and , by a route involving reaction of R'X with mononuclear intermediates.

Reaction of HCl with photoproduced base-substituted manganese carbonyl radicals

Near-UV irradiation of Mn2(CO)8L2 (L = PBu3, P(OEt)3) in the presence of HCl and a variety of solvents yields both HMn(CO)4L and Mn(CO)4(L)Cl. Evidence suggests the mechanism involves oxidative addition of HCl to 15- and 17-electron metal carbonyl radicals.
