Reaction of 2,3-bis(methylthio)pyrrolo[1,2-a]benzimidazol-1-one with BrRe(CO)3(THF)2: X-ray diffraction structure, redox chemistry, and luminescence behavior of fac-BrRe(CO)3{N,S-2,3- bis(methylthio)pyrrolo[1,2-a]benzimidazol-1-one}

The reaction of the heterocyclic ligand 2,3-bis(methylthio)pyrrolo[1,2-a] benzimidazol-1-one with the rhenium(I) compound BrRe(CO)3(THF) 2 has been explored and found to give the new complex fac-BrRe(CO)3(N,S-heterocycle) (1) upon stirring at room temperature. The same product has also been isolated in lower yield by heating BrRe(CO) 5 and the starting heterocycle. Compound 1 has been isolated and characterized in solution by IR and NMR spectroscopies, and the N,S-chelation mode exhibited by the ancillary heterocyclic ligand has been confirmed by X-ray diffraction analysis. The redox properties of 1 have been investigated by cyclic voltammetry, where an irreversible reduction is observed at Epc=-0.63V. The nature of the LUMO in 1 has been evaluated through the means of extended Hückel MO calculations, and the electrochemical and MO data are discussed relative to the parent heterocyclic ligand that possesses a low-lying, ligand-based π* LUMO. The photophysical behavior of the starting heterocycle and compound 1 has been analyzed in CH2Cl2 and MeCN solvents; emission quantum yields at room temperature are on the order of 10-5 in CH2Cl2 and one order of magnitude higher in MeCN. The lowest excited state arises from an intraligand (IL) transition resulting from a π → π* excitation that is confined to the heterocycle.
A mechanistic investigation of the photoinduced reduction of carbon dioxide mediated by tricarbonylbromo(2,2′-bipyridine)rhenium(I)

A mechanistic study of the photoinduced reduction of carbon dioxide to carbon monoxide in the triethanolamine/dimethylformamide/ReBr(CO)3(bpy) (bpy is 2,2′-bipyridine) system is described. Continuous photolysis at 436 nm results in the highly specific formation of CO with a quantum yield, φCO, that reaches 0.15. The value of φCO decreases with increasing triethanolamine concentration in the range 0.75-3.8 M; addition of 10% water to the solvent medium also lowers φCO. Luminescence measurements reveal that triethanolamine reductively quenches the Re-to-bpy charge-transfer excited state of ReBr(CO)3(bpy) with a rate constant of 6 × 107 M-1 s-1, whereas CO2 undergoes no discernible interaction with the photoexcited complex. Formation and decay of the initial reduction product [ReBr(CO)3(bpy)]- have been observed in flash photolysis experiments. The amount of [ReBr(CO)3(bpy)] produced correlates with the value of CO2 thereby implicating this 19e complex in the mechanism of CO2 reduction. Evidence that [ReBr-(CO)3(bpy)]- reacts directly with CO2 has been obtained, although the identity of the resulting product is unknown at present.
A Water-Soluble Rhenium(I) Catalyst for the Regio- And Stereoselective C(sp2)-H Alkenylation of N-Pyridyl-/ N-Pyrimidylindole and the N-H Alkenylation of N-Pyrimidylaniline Derivatives with Ynamides

A water-soluble and low-valent rhenium(I) catalyst for the C2 alkenylation of N-pyridyl/N-pyrimidylindole derivatives with ynamides under mild conditions using water as the solvent has been described. The reaction of N-pyridyl/N-pyrimidyl indole with the ynamide afforded the C2-Z-selective alkenylation derivative as the sole product, and the reactions of N-pyrimidylanilines delivered the corresponding N-alkenylated product rather than the expected C-H alkenylation products in high yields under the same conditions.
