摘要

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 CoCl 2 as an additive.
