Rhodium-catalyzed reactions of cyclobutanones with alcohols and amines forming esters and amides
Cyclobutanones react with alcohols in the presence of rhodium(I)-phosphine catalysts to give esters in good yields through an addition/ring-opening process. Amides are formed by a similar reaction with amines.
