Ketone-directed Ru(0)-catalyzed hydroarylation of alkynes enabled by in situ generation of a Ru(0) catalyst from an air-stable, inexpensive and user-friendly Ru(II) precatalyst is reported.
Cationic Ir complex ([Ir(cod)2]BF4 + BINAP) catalyzed the addition of ortho-C–H bonds in arylketones to alkynes, which gave alkenylated products in good to high yield. Styrene derivatives were good substrates, and the enantioselective addition to norbornene was also described.

This invention relates to a method for producing a ruthenium catalyst in which ruthenium supported on at least one metal oxide is pretreated with an aldehyde compound, a phosphorus compound, and a lower alcohol compound, and a method for producing alkyl- or alkenyl-substituted compound using the ruthenium catalyst.
