heterogeneous gold(I)-catalyzed regioselective hydration of propargylacetates has been developed that proceeds smoothly in 1,4-dioxane at room temperature in the presence of 1 mol% diphenylphosphine-modified MCM-41-anchored gold(I) complex [Ph2P-MCM-41-AuSbF6] as catalyst and provides an efficient and practical approach for the synthesis of a variety of α-acyloxy methyl ketones with high atom economy
Indazolin-<i>s</i>-ylidene–N-Heterocyclic Carbene Complexes of Rhodium, Palladium, and Gold: Synthesis, Characterization, and Catalytic Hydration of Alkynes
properties of these complexes were modified by the introduction of different substituents at the coordinated NHC ligands. Catalytic properties of the goldcomplex were evaluated in the hydration of alkynes to give the corresponding ketone products. This new type of gold N-heterocyclic carbenecomplex showed a high catalytic activity in the hydration of alkyne at roomtemperature.
