We have found that expanded-ring NHC gold(i) complexes efficiently and regioselectively catalyze the hydration of alkylarylacetylenes in an anti-Markovnikov fashion due to steric repulsion build-up in the transition state, giving benzylalkyl ketones.

An efficient one‐pot methodology for the preparation of 5‐amino‐1,2,3‐triazole derivatives based on the combination of dipolar azide−nitrile cycloaddition with Dimroth rearrangement under solvent‐free conditions has been developed.

Novel α-CF3-substituted E-dehydroornithine derivatives have been synthesized via the Cu(i)-catalyzed hydroamination of α-CF3-α-allenyl-α-aminocarboxylates/phosphonates with different amines.
