The compounds bis(benzotriazol-1-yl)phenylmethane and bis(benzotriazol-1-yl)pyridin-2-ylmethane were prepared by reacting (benzotriazol-1-yl)methanone and benzaldehyde or pyridine-2-carboxaldehyde using CoCl2 as catalyst under neat conditions. The products were characterized spectroscopically and the solid-state structures were ascertained by single-crystal X-ray diffraction.
