The present invention relates to a process for the regioselective synthesis of compounds of the formula (I), wherein R0; R1; R2; R3; R4; R5; A1; A2; A3; A4; Q and J have the meanings indicated in the claims. The present invention provides a direct copper catalyzed regioselective process to a wide variety of unsymmetrical, multifunctional N/-substituted benzimidazoles or azabenzimidazoles of formula I starting from 2-halo-nitroarenes and N/-substituted amides. The process is useful for the production of pharmaceuticals, diagnostic agents, liquid crystals, polymers, herbicides, fungicidals, nematicidals, parasiticides, insecticides, acaricides and arthropodicides.

Page/Page column 38, (2010/02/14)
A novel derivative of heterocyclic compound having nitrogen atom with a structure made by bonding special groups to benzimidazole, a material for an organic electroluminescence (EL) device comprising the derivative of heterocyclic compound having nitrogen atom and an organic electroluminescence device comprising at least one organic compound layer containing a light emitting layer sandwiched between a pair of electrodes, wherein the device contains the derivative of heterocyclic compound having nitrogen atom. An organic EL device achieving elevation of luminance and of efficiency in light emission even under low driving voltage is obtainable by an employment of the derivative of heterocyclic compound having nitrogen atom for at least one layer composing organic compound layers of the EL device.

, p. 206 - 207 (2007/10/03)
N-Arylation of benzoazoles with diaryliodonium salts can be performed in good yields in the room-temperature ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim]BF4), which provides an efficient method for the synthesis of N-arylbenzoazoles. The ionic liquid can be recycled and reused.
