CYCLIC DINITRONE COMPOUND AND PROCESS FOR PRODUCING THE SAME

摘要

A cyclic dinitron compound is produced by stirring a cyclic nitron compound-containing solution in the presence of an acid catalyst to selectively conduct a ring enlarging dimerization reaction. The cyclic nitron compound is more preferably a five- to ten-membered ring compound. The above solution is more preferably a chloroform solution. The acid catalyst is more preferably a p-toluenesulfonic acid monohydrate. The reaction temperature is more preferably in the range of 0 to 50°C. Thus, for example, it is possible to provide a production process that can simply and efficiently produce a large-ring (ten- or larger- membered ring) cyclic dinitron compound, which is important as a precursor of large-ring (ten- or larger- membered ring) cyclic diamine compounds and cyclic dihydroxyamine compounds containing a various substituents expected to be utilized as ligands of metal complexes and various functional materials.
