Assignments of the Carbon Resonances in tert-Butylated 2-Naphthols by the Two-Dimensional C-Relayed H,C-COSY Technique

The signals of the aromatic carbon atoms in three tert-butylated 2-naphthols were assigned by the new two-dimensional NMR technique C-relayed H,C-COSY.The aplication of only one-bond coupling constants avoids any ambiguities in the assignment.A number of previous assignments had to be changed.The chemical shift values and one-bond C-C coupling constants have been correlated with electron densities and bond orders, respectively.
