Evidence for a Nonclassical Structure of a 1,6-Methano(10)Annulene - A Cryogenic C-13 CPMAS NMR-Study of the 11,11-Dimethyl Derivative
High-resolution C-13 NMR spectra obtained using cryogenic CPMAS methodology at temperatures as low as 10 K suggest that the structure of 11,11-dimethyl-1,6-methano[10]annulene is nonclassical.
