(Chemical Equation Presented) A large range of benzoins was successfully applied as C-nucleophiles in the palladium-catalyzed allylic alkylation with several allyl acetates, resulting in functionalized tertiary homoallylic alcohols. A number of unsymmetrical benzoins can be coupled with high levels of regio- and chemoselectivity. Finally, the challenging compatibility of free N-heterocyclic carbenes with a palladium catalyst has been utilized in a number of metal- and organocatalyzed three-component coupling reactions.

Allthough the photochemically induced reaction of benzil with allyltrimethylstannane in benzene afforded α-allylbenzoin as a major product, benzil did not react thermally with the same reagent.An ESR observation disclosed that the benzil anion radical ion

Irradiation of an acetonitrile solution of benzils and acenaphthenequinone in the presence of allylic stannanes afforded homoallylic alcohols in good yields.In the reaction with unsymmetric allylstannanes, the allylic groups were introduced predominantly at α-positions.The completely regioselective introduction could be achieved by the irradiation in the presence of NaOH or CoCl2 as an additive.
