Abstract: Processes for selectively hydrogenating double and/or triple bonds in organic molecules include providing at least one organic molecule containing a double and/or triple bond, providing at least one hydrogen donor molecule, and hydrogenating the double and/or triple bond in the presence of at least one catalyst. Processes for preparing arylamine molecules include selectively hydrogenating double bonds in arylamine compounds by providing at least one organic molecule containing a multiple bond, providing at least one hydrogen donor molecule, and hydrogenating the multiple bond in the presence of at least one catalyst. The processes provide efficient, cost-effective and safe methods for conducting selective hydrogenation reactions in the synthesis of organic molecules, such as charge-transport molecules.

Abstract: A process comprising for example reacting a substituted or unsubstituted arylamine or a mixture thereof with a Vilsmeier reagent in a solvent system comprising acetonitrile as a sole solvent or a solvent system comprising acetonitrile and one or more solvents selected from toluene, xylene, chlorobenzene, dichlorobenzene, dichloromethane, 1,2-dichloroethane, or a combination thereof.
