Sulfones and their derivatives serve as important structural units in organic chemistry. However, synthesis methods for these compounds have remained limited and complex. Researchers recently reported a photoredox/copper dual catalysis system. This system enables the 2,2-diarylethyl sulfones synthesis through 1,2-arylsulfonylation of vinylarenes. The developed protocol features high reaction regioselectivity and good reaction generality. Consequently, it provides a facile approach to producing these chemical units.

Advancing 2,2-diarylethyl sulfones synthesis

Sulfone molecules are highly significant in the pharmaceutical industry. For instance, clinicians use them to treat bacterial infections like leprosy. Furthermore, some diarylsulfones act as nonnucleoside antiviral inhibitors for HIV research. Therefore, a simplified synthetic method is crucial for drug discovery. The use of photoredox and copper catalysis allows for mild reaction conditions. This efficiency helps chemists create more diverse drug candidates rapidly.

Frequently Asked Questions
