A novel
series of Indy-N-heterocyclic carbene ligands (Indy = indazolin-<i>s</i>-ylidene) have been developed and investigated. Via a mild
Ag carbene transfer route, these new carbene ligands reacted with
rhodium, palladium, and gold salts to yield the corresponding air-stable
metal complexes. The product complexes were characterized by NMR spectroscopic
methods and X-ray diffraction analysis. The electronic properties
of these complexes were modified by the introduction of different
substituents at the coordinated NHC ligands. Catalytic properties
of the gold complex were evaluated in the hydration of alkynes to
give the corresponding ketone products. This new type of gold N-heterocyclic
carbene complex showed a high catalytic activity in the hydration
of alkyne at room temperature.
