Abstract
The first synthesis of noncoordinating meso-aryl-subporphyrin cation was achieved by the reaction of methoxo-5,10,15-triphenylsubporphyrinateboron(III) and hexabromocarborane triethylsilylium complex in toluene at room temperature for 3 hours. The cation complex was fully characterized by 1H NMR, 11B NMR, ESI-TOF MS spectroscopy and X-ray diffraction analysis. The solid state structure of subporphyrin cation exhibits planar conformation, which is sharply contrasted with the bowl-shaped structure of neutral boron-methoxy substituted subporphyrins.
