Aromatic Compounds

特許 権利維持 In organic chemistry, aromaticity is a chemical property describing the way in which a conjugated ring of unsaturated bonds, lone pairs, or empty orbitals exhibits a stabilization stronger than would be expected by the stabilization of conjugation alone. The earliest use of the term was in an article by August Wilhelm Hofmann in 1855.[1] There is no general relationship between aromaticity as a chemical property and the olfactory properties of such compounds.
