✦ Synopsis

A ^13^ C NMR spectral study of 29 arylporphyrin derivatives is presented. In all of the tetrasubstituted and trisubstituted compounds examined the α- and β-carbons exhibited the expected broadened signals. In complete contrast, the diphenylporphyrins all showed sharp α- and β-carbon peaks which facilitated structural confirmation. These observations have been correlated with differing tautomeric exchange rates.

A new 13C N M R method based on solvent effects allows the identification of carbon atoms a to a carbonyl group. With a simple change in solvent from CDCl, to CDC1,-dioxane (1:4), the -C absorption for all carbons except those a to the carbonyl group in the compounds under study were displaced to lo
