Mild Hydrosulfenylation of Olefins under Neutral Conditions Using a Defined NHC-Ligated Iron–Sulfur Catalyst

Abstract

A defined NHC-Fe–S complex proved to be an efficient catalyst for the selective hydrosulfenylation of α,β-unsaturated ketones or vinylnitriles. A wide range of different aliphatic thiols were transferred in this atom-economic reaction into the corresponding thioethers. Mild reaction conditions, equimolar amounts of substrates, low catalyst loadings, and mild reaction conditions are characteristic for this transformation.
