Water-promoted C-S bond formation reactions
Nature Communications, 2018 Despite the biological importance of sulfones, available synthetic methods usually involve toxic metals and reagents or harsh conditions. Here, the authors report an environmentally benign procedure for the metal-free carbon-sulfur bond formation of ...

Transient Sulfenic Acids in the Synthesis of Biologically Relevant Products
Molecules, 2018 Sulfenic acids as small molecules are too unstable to be isolated and their transient nature offers the possibility to involve them in concerted processes that lead to the obtainment of functional groups such as sulfoxides, sulfones, and disulfides.

Desulfonylative Arylation of Redox-Active Alkyl Sulfones with Aryl Bromides
, 2019 Herein we describe the development of the first reductive cross-electrophile coupling between alkyl sulfones and aryl bromides. The use of alkyl sulfones as coupling partners offers strategic advantages over other alkyl electrophiles used in reductive ...
