We have investigated the role of ring sizes and substituents in NHC ligands in some (NHC)Au(I) complexes in the hydration of internal alkynes. Despite the fact that using (NHC)Au(I) complexes in the hydration of diarylacetylenes leads to Markovnikov-type products, the precise tuning of ligands allows changing the regioselectivity in arylalkylacetylene hydration to the anti-Markovnikov-type.

The reaction of direct photoinitiated iodosulfonylation of internal acetylenes with p-tolylsulfonyl iodide and its regioselectivity of the products was studied. Methods for the subsequent functionalization of β-iodovinylsulfones using cross-coupling reactions to obtain valuable and non-available compounds are proposed.
