Versatile and practical : Intermolecular hydroacylation of internal alkynes takes place in the presence of Ru catalysts together with HCO 2 Na and Xantphos to give the corresponding conjugated enones. Aromatic aldehydes with or without coordinating groups could be used in the present catalytic system. The solid Ru/CeO 2 catalysts can be recycled for several times without significant decreases in yield (see scheme).
