The gold-catalyzed intermolecular addition of 1,3-dicarbonyl compounds to unactivated 1-alkynes (Nakamura reaction) is achieved at room temperature for the first time through synergistic gold/gallium catalysis. The developed system is highly efficient wit

The hydro(trispyrazolyl)borato-ruthenium(II) diphosphinoamino complex TpRu[4-CF3C6H4N(PPh2) 2](OTf) (I) [Tp=hydro(trispyrazolyl)borate] catalyzes the Markovnikov addition of β-diketones to unactivated 1-alkynes in good to excellent yields. The reaction proceeds under solvent-free and additive-free conditions and the catalyst loading can be reduced down to 0.4amol%. Complex I (1amol%) also catalyzes the addition of secondary amines to aromatic terminal alkynes, unusual anti-Markovnikov products are exclusively formed.
