regioselective addition of 1,3-dicarbonyl compounds to internal alkynescatalyzed by rhodium/Lewisacid catalysts. The corresponding branched/linear allylic alkylation products could be selectively obtained in good yields. Rh–H species were considered to be generated by direct C–H oxidative addition of 1,3-dicarbonyl compounds with rhodium catalyst with the assistance of Lewisacid. Moreover, a retro-allylic
