series of variously functionalized alkylbenzylketones. A large range of functional groups were well tolerated on the ortho‐, meta‐ and para‐positions by this mild process regardless of their electronic effects, demonstrating the general character of the present methodology. The trimethylsilylchloride/sodium iodide reducing process was also successfully applied to reduce α‐ketoacid and α‐ketoester substrates
Treatment of α,β-epoxy sulfoxides with excess sodium phenylselenide and various kinds of alkylthiolates gave dialkyl ketones and α-sulfenylated carbonylcompounds, respectively, in good yields under mild conditions.

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.
