Technical Notes:

1.Catalyst used in the selective hydration of substituted alkynes at room temperatures.

2.Catalyst used in the hydroarylating/aromatization of arene-diynes.

3.Highly-efficient and regio-selective catalyst for the selective carbonyl migration in alkynyl-substituted indole-3-carboxamides.

4.intermolecular gold(1) catalyzed alkyne carboalkoxylation reactions for the multicomponent assembly of B-alkoxy ketones.

5.Gold(1)-catalyzed hydration of alkynylphosphonates: Efficient access to B-ketophosphonates

6.Gold-catalyzed intramolecularhydroamination reaction.
