Rhenium complexes dimethylformamide

Recently, the interest in Re (I) complexes has been increased due to their potential utility for the activation and reduction of C02 into CO and C032 in a purpose of construction of artificial photosynthetic systems [11-13]. Rhenium Complexes such as ReX(CO)3(bpy) (X=C1, Br) and Re(CO)2(bpy)[P(OEt)3]2 have been used as photocatalysts for C02 reduction to CO in solvent mixture of triethanolamine/dimethylformamide [12,13]. Most of the research on photochemical activation and reduction of C02 using Re(I) complexes have focused on the homogeneous solution systems. There are few reports concerned about the encapsulation of rhenium complexes into molecular sieves and their photochemical application to the photochemical reduction of C02. 

Selective carbon dioxide reduction to CO has been accomplished in a non-aqueous medium that includes tricarbonyl (2,2 -bipyridinium) rhenium , /ac-Re(bpy) (CO)3X (X=Cl, Br) as light-active component and homogeneous catalyst for C02 reduction [183-185]. In dimethylformamide solutions that include TEOA as sacrificial electron donor, photosensitized reduction of C02 to CO proceeds with a quantum efficiency of

Mechanistic investigations have revealed that reductive ET quenching of the rhenium complex (Eq. (54)) yields the catalytic intermediate active in deoxygenation of C02. It has been suggested that carbon...
