Catalyst-Free Synthesis of Phosphinochalcogenoic Anhydrides via Oxygen–Chalcogen Exchange with Elemental Sulfur or Selenium

LZLongzhi ZhuSXShuangjiao XieHYHongbo Yang

Key Points

  • The aim is to create a new method for synthesizing phosphinothioic and phosphinoselenoic anhydrides without using catalysts.
  • Developed a three-component synthesis approach.
  • Utilized elemental sulfur or selenium along with acyl chlorides and H-phosphine oxides.
  • Conducted reactions under catalyst-free conditions.
  • Successfully synthesized phosphinothioic and phosphinoselenoic anhydrides.
  • Demonstrated efficiency in using sulfur and selenium for the synthesis process.

Abstract

A novel catalyst-free, three-component strategy for the synthesis of phosphinothioic/phosphinoselenoic anhydrides has been developed, employing elemental sulfur or selenium, acyl chlorides (or anhydrides), and H-phosphine oxides. This protocol operates under...
