Alkyne-gold hydrothiolation

Corma A, Gonzalez-Arellano C, Iglesias M, Sanchez R Efficient synthesis of vinyl and alkyl sulfides via hydrothiolation of alkynes and electron-deficient olefins using soluble and hetereogeneous gold complexes catalysts. Appl. Catal. A 2010 375 49-54. 

Hydroamination of aUcynes using gold catalysts has also attracted considerable interest [155-158]. hi this context, triazole-Au(l) complexes, which show improved thermal stability, are active catalysts for the hydroamination of alkynes [159]. The hydrothiolation of alkynes using soluble and heterogenized gold complex catalysts was reported by Corma and co-workers [160].
