    摘要: The present invention provides a process for preparing monoiodinated aromatic compounds that are useful as intermediates for preparing charge transporting and hole transporting amino compounds and have high purity with high yield and at low cost. A process for preparing aryl iodide compounds comprises reacting an aryl halide compound with a metal iodide, a metal catalyst and a catalyst coordinating ligand in at least one solvent to form an aryl iodide; and purifying the aryl iodide. A triarylamine compound and a process for preparing a triarylamine compounds reacting the aryl iodide with a diarylamine is also provided. Further, a photoconductive imaging member comprising a charge transport layer that comprises at least one triarylamine compound prepared reacting the aryl iodide with a diarylamine is provided.
