Enabling reactions of traditional substrates that are inert to Pd catalysts has the potential for further advancements in the field of Pd chemistry. In this study, we developed a method for generating ketyl radicals through the reaction of a photoexcited Pd species with ketones. Upon subsequent reaction with olefins, the ketyl radicals generated through this method yielded Pd-specific reductive and

A cationic Pd(II)-catalyzed reductivecyclization of alkyne-tethered ketones or aldehydes usingethanol as hydrogensource under mild conditions was developed. The reaction is an environmentally benign synthetic method and proceeds efficiently to give useful N-heterocycles or carbocycles bearing an exocyclic double bond and a hydroxyl group in high yield.
