Bromination of Molybdenum Carbonyls revisited: Oxo Complexes and Routes toNew Materials Chemistry

The use of in situ 2> led to considerably improved preparations of for which the rate of decarbonylation to is greatly increased by refluxing under reduced pressure (15-20 mmHg).Attempts to prepare 2> by Br2 addition to cis- or trans-2> led to .The OP(C6H11)3 complex may be used as a catalyst for the epoxidation of cyclohexene or for the addition of singlet oxygen to α-terpinene (1-isopropyl-4-methylcyclohexa-1,3-diene).The species > was adsorbed onto sodium montmorillonite in a new type of reaction for sodium montmorillonite involving multiple abstractions of NaBr from the complex anion.In solution > also decomposes to crystalline 2> which is monoclinic, space group C2/c .

Kinetic and spectroscopic studies of Mo(CO)2(PR3)2Br2 compounds

Flash-photolysis and stopped-flow experiments are reported for a series of aryl-, alkyl-, and mixed aryl-alkylphosphine derivatives of Mo(CO)3(PR3)2Br2. The photochemically generated dicarbonyl transient rapidly recombines with carbon monoxide under a CO atmosphere to re-form the tricarbonyl via the rate law R = k[Mo(CO)2(PR3)2Br2][CO]. Bimolecular rate constants between 2.5 × 103 and 7.3 × 105 M-1 s-1 were measured in 1,2-dichloroethane. The natural logarithm of the rate constants for CO recombination fit a two-parameter free energy relationship based on the electronic and steric nature of the phosphines. Electron-donating and sterically bulky phosphines inhibit reaction. There is a pronounced solvent effect on the reactivity and the electronic spectrum of dicarbonyl compounds. Hexane as solvent accelerates the reaction while methanol essentially quenches it relative to 1,2-dichloroethane. Electronic spectral measurements show that λmax for the HOMO-LUMO transition shifts from 570 nm in CH2Cl2 to 755 nm on Teflon (diffuse-reflectance spectrum). These observations are consistent with solvent interaction with the LUMO.
