  A naphthalene derivative represented by the following formula (1) is provided. In the formula, Ar 1 to Ar 4 each represent an aromatic hydrocarbon cyclic group having 6 to 18 carbon atoms forming a ring. The aromatic hydrocarbon cyclic group has none of anthracene skeleton, pyrene skeleton, aceanthrylene skeleton and naphthacene skeleton. n, m and 1 each represent an integer in a range of 1 to 5. p represents an integer in a range of o to 5. When n, m, 1 and p each are 2 or more, a plurality of Ar 1 to Ar 4 may be mutually the same or different.

  combination of N 1 /N 2 chemoselectivity on the amidine and reactivity-controlled X 1 /X 2 chemoselectivity on the 1,2-dihaloarene. This reaction proves to be fairly general for the regiospecific synthesis of 1,2-substituted benzimidazoles.

  New, improved conditions have been developed and optimized for the synthesis of benzimidazoles by intramolecular palladium-catalyzed aryl-amination chemistry. This methodology, combined with a "catch and release" purification strategy, has led to a range of these heterocycles being prepared rapidly and in excellent yield.
