An efficient palladium-catalyzed cross-coupling of indium homoenolate with arylhalide is described. The reactions proceeded efficiently in DMA at 100 °C to afford the desired products of β-aryl ketones in moderate to good yields. Various important functional groups including COR, COOR, CHO, CN, OH, and NO2 can be well tolerated in the protocol.
of aryl bromides with primary and secondaryallylicalcohols, performed in the presence of an air-stable phosphinito complex of palladium(II), produced the corresponding carbonylcompounds. Reactions with tertiary allylicalcohols under the same conditions generated the aromatic conjugated alcohols. allylicalcohols - Heck reaction - palladium - aldehydes - ketones
