摘要:The present invention relates to a process for the regioselective synthesis of compounds of the formula I, n nwherein 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 palladium 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 useful for the production of pharmaceuticals, diagnostic agents, liquid crystals, polymers, herbicides, fungicidals, nematicidals, parasiticides, insecticides, acaricides and arthropodicides.
