A convergent paired electrolysis catalyzed by a B12 complex for the one-pot synthesis of a tertiary amide from organic trichlorides (R-CCl3) has been developed. Various readily available organic trichlorides, such as benzotrichloride and its derivatives, chloroform, dichlorodiphenyltrichloroethane (DDT), trichloro-2,2,2-trifluoroethane (CFC-113a), and trichloroacetonitrile (CNCCl3), were converted to amides in the presence of tertiary amines through oxygen incorporation from air at room temperature. The amide formation mechanism in the paired electrolysis, which was mediated by a cobalt complex, was proposed.

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.

A series of 2,3,3a,4-tetrahydro-1H-pyrrolo[3,4-c]isoquinolin-5(9bH)-ones is described, several examples of which exhibit potent 5-HT2C agonism with excellent selectivity over the closely related 5-HT2A and 5-HT2B receptors. Compounds such as 38 and 44 were shown to be effective in reducing food intake in an acute rat feeding model.
