## Abstract Three α‐cyclopropyl β‐dicarbonyl compounds have been used as probes for α‐radicals as electrophilic reaction intermediates in a cerium‐catalyzed α‐hydroxylation reaction with molecular oxygen. Since the cyclopropyl group did not ring‐open to products with a butenyl moiety, but was retai
