Technical Notes:
1.Catalyst used for the selective hydration of substituted alkynes at room temperature without acidic promoters .
2.Gold(I) catalyzes bromination of terminal alkynes .
3.Sequential O-H/C-H bond insertion of phe nols initiated by the gold(I) - catalyzed cyclization of 1-bromo-1，5-enynes
4.L igand- controlled gold catalyzed cycloisomerization of 1,n-enyne esters toward synthesis of dihydronaphthalene.
