Abstract

The hybrid catalyst composed of the B12 complex and rhodium ion (Rh3+) modified titanium oxide was synthesized for the visible light-driven B12 inspired catalytic reaction. The hybrid catalyst contains 4.93 × 10−6 molg−1 of the B12 complex and 5.43 × 10−5 molg−1 of the Rh(III) ion on the surface of titanium oxide. Visible light irradiation (λ ≧ 420 nm) of the hybrid catalyst in the presence of triethylamine (Et3N) as a sacrificial reagent showed absorption at 390 nm, typical for the Co(I) state of the B12 complex monitored by diffuse reflectance UV–vis analysis, which imply that electron transfer from the titanium oxide to Co(III) center of the B12 complex occurred by the visible light irradiation. Benzotrichloride was converted to N,N-diethylbenzamide by the visible light irradiation catalyzed by the hybrid catalyst in air at room temperature. Both the conduction band electron and valence band hole of the catalyst were utilized for the reaction to form the amide product. The reaction mechanism of the duet reaction was proposed.
