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
