US 2013/0324768 A1 · CARBON NANORING AND METHOD FOR PRODUCING A RING-SHAPED COMPOUND SUITABLE AS A STARTING MATERIAL FOR PRODUCTION OF THE SAME

Abstract

The present invention produces Cyclic Compound (1) in which organic ring groups including cyclohexane rings and benzene rings are continuously bonded, using a compound having at least one cyclohexane ring and benzene rings with halogen atoms at the two terminuses, in the presence of a nickel compound (bis(1,5-cyclooctadiene)nickel, etc.). Thereafter, by converting the cyclohexane rings in Cyclic Compound (1) into benzene rings, a desired carbon nanoring can be obtained. Thereby, the present invention efficiently produces a carbon nanoring made of a compound having a cyclic structure in which a desired number of organic ring groups are continuously bonded, with a short production process.
