PROBLEM TO BE SOLVED: To provide azacalixpyridine which is a new cyclic compound and used as a host molecule of an inclusion compound. SOLUTION: This azacalixpyridine comprises the cyclic compound composed of 4,6-repeating structure units of the pyridines and is expressed by chemical formula (I) (R is a 1-6C alkyl) or chemical formula (II). The azacalixpyridine is formed by conducting condensation reaction of a 2,6-dihalogenated pyridine with a 2,6-di(alkylamino)pyridine (composed of 1-6C alkyls), or of a 2- dihalogenated 6-alkylamino pyridine (composed of a 1-6C alkyl), in the presence of a palladium complex catalyst. The azacalixpyridine newly produced makes it possible that lone pairs of electrons are integrated inside a cyclic skeletal structure thereof and an atom or a molecule having Lewis acid nature is included in the azacalixpyridine. Therefore, a new metal complex catalyst and a charge-transfer complex are each provided. COPYRIGHT: (C)2003,JPO
