Indium-mediated allylation of 1,2-diketones

Indium-mediated allylation of 1,2-dicarbonyl compounds with indium and allylic bromides was achieved in the presence of nBu4NI or NH4Cl as additive to afford mono- and/or diallylated products in good yields.

Allylation of α-Diketones by Photochemical Reactions with Allylic Stannanes. Regiochemistry of Introduced Allylic Group

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.
