imply that electron transfer from the titanium oxide to Co(III) center of the B12 complex occurred by the visiblelightirradiation. Benzotrichloride was converted to N,N-diethylbenzamide by the visiblelightirradiation 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
was developed. It provides a convenient and efficient way to synthesize amides. Based on this method, trichlorinated organic compounds were converted into amides in the presence of an amine under aerobic conditions at room temperature in a one-pot procedure. Various trichlorinated organic compounds and an amine source, such as primary, secondary, and cyclic amines, have been evaluated for this transformation
