The rhenium heptahydride complex [ReH7(PCy3)2] was found to be an effective homogeneous catalyst for amination of various alcohols through hydrogen transfer mechanism. Under carbonmonoxide atmosphere, a variety of primary and secondary alcohols could directly undergo the CN coupling process.
A long‐awaited asymmetric version of the intramolecularhydroarylation of alkynes to form fused ring systems has been developed. A cationic palladium(II)/(S)‐xyl‐H8‐binap complex was used to catalyze an enantioselective hydroarylation of alkynes at room temperature to furnish axially chiral 4‐aryl 2‐quinolinone derivatives in good yields with good enantioselectivity (see scheme; Bn=benzyl).
