1,2-Naphthoquinone with γ-substituted allyltin reagents undergoes both thermal and photochemical reactions, which show the opposite regioselectivities to each other. The both reactions are supposed to proceed via the initial 1,2-addition, which occurs at

Allyl- and benzyl-trifluoroborates can be applied to the photoreaction of carbonyl compounds to afford the corresponding alcoholic adducts in acceptable yields via a photo-induced single electron transfer pathway. The results were confirmed from the react

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.
