Perdeuteration of Deactivated Aryl Halides by H/D Exchange under Superelectrophile Catalysis

Superelectrophilic silylium/arenium ions are shown to be highly effective H/D exchange promoters for the exhaustive deuteration of electron-deficient aryl halides. Several of the resulting perdeuterated aryl halides have been previously inaccessible with existing deuterium-labeling procedures. Using inexpensive C6D6as the deuterium source, excellent degrees of deuterium incorporation were achieved under ambient reaction conditions. Importantly, the perdeuteration remains unaffected on multigram scale, even at a reduced catalyst loading of 0.1 mol %. By this method, otherwise expensive or noncommercially available NMR solvents such as 1,2-dichloro- and 1,2-difluorobenzene can be prepared.

COMPOUND WITH TRIPHENYLAMINE STRUCTURE, AND ORGANIC ELECTROLUMINESCENT ELEMENT

Problem to Be Solved: There is provided an organic compound of excellent characteristics that exhibits excellent hole-injecting/transporting performance and has an electron blocking ability and a highly stable thin-film state with excellent heat resistance. The compound is provided as a material of a high-efficiency, high-durability organic EL device, and is used to provide a high-efficiency, high-durability organic EL device. Solution: The compound of the present invention is an arylamine compound of general formula (1) or (2) having a triphenylamine structure. The arylamine compound is used as a constituent material of at least one organic layer in an organic electroluminescent device that includes a pair of electrodes, and one or more organic layers sandwiched between the pair of electrodes.
