Overview

Photocatalytic hydropentafluorosulfanylation produces alkynes in good yields, suggesting sulfur hexafluoride may enable safer alternatives.

Key Points

  • The method yields pentafluorosulfanylated alkenes with good to excellent efficiency, advancing new synthetic routes.
  • Photocatalytic techniques utilizing visible-light photoredox catalyst and a reductant were employed for the process.
  • Catalytic systems were designed to address challenges posed by sulfur hexafluoride's high stability and low redox potential.
  • Findings support the potential for less toxic methods for synthesizing SF5-bearing organic compounds.
