A heterogeneous system Fe(CrO2)2–TiO2/X (where X is promoter NiO, CuO, ZnO, Cr2O3, Fe2O3, PrOCl, TbOCl, LaOCl, or EuOCl) was prepared. The photocatalytic activity of the system was tested in the tandem reaction of primary alcohols (BnOH, EtOH) with arylamines aimed at synthesizing benzamides and substituted 2-methylquinolines under aerobic conditions at room temperature.

The preparation of methylene-bridged C2-symmetric nitrogen-heterocycles as a new class of ligands is described, including methylene-bridged pyridines, quinolones, piperidines and pyrrolidines. These methylene-bridged aromatic systems are obtained via a microwave assisted Ziegler-type reaction. The separation of diastereomers and the application of the copper complexes of these ligands for cyclopropanation reactions proves the applicability of these new types of ligands.
Fe(CrO2)2-catalyzed, photoactivated oxidative one-pot tandem synthesis of substituted quinolines from primary alcohols and arylamines

[Figure not available: see fulltext.] A one-pot tandem synthesis of substituted quinolines involving selective catalytic oxidation of primary alcohols to the corresponding aldehydes and their subsequent condensation with arylamines has been developed. Fe(CrO2)2 has been used as a catalyst, and oxidation has been performed with aqueous H2O2. To accelerate the catalytic oxidation of alcohols, photoactivation method has been applied.
