Abstrakt: Novel approach with amide-tethered H-bond donor NHC ligands enabled Au(I)-catalysis via H-bonding. The plain NHC-Au(I)-Cl complex catalysed conversions of terminal N-propynamides to oxazolines, and enyne cycloisomerization with an acid additive, in DCM at RT. DFT calculations enlightened the function of the side-arm in the activation.Novel approach with amide-tethered H-bond donor NHC ligandsenabled Au(I)-catalysisviaH-bonding.
