Chemists settle 50-year debate on bonding structure of the 2-norbornyl cation

07/8/2013 | Chemical & Engineering News

German researchers may have resolved a 50-year debate by determining the 2-norbornyl cation has two electrons delocalized over three carbon atoms, rather than shared by two carbon atoms. Chemists at the University of Erlangen-Nuremberg and the University of Freiburg used a deep-freeze crystallization process to make the determination. Theoretical organic chemist Dean J. Tantillo of the University of California, Davis, described the work as "a triumph of creative crystallography in taming an uncooperative cation."
