Sulfur Trioxide Pyridine Complex: A Versatile Reagent for Sulfonation Reactions
Sulfur trioxide pyridine complex (SO₃•Py) is a widely used sulfonating reagent in organic synthesis. This stable, crystalline solid provides a safer and more manageable alternative to gaseous sulfur trioxide (SO₃) or chlorosulfonic acid, making it ideal for various chemical transformations. It plays a crucial role in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals by…
