Abstract

High-surface-area β-MnO₂ (β-MnO₂-HS) nanoparticles could act as effective heterogeneous catalysts for the one-pot oxidative sulfonamidation of various aromatic and heteroaromatic thiols to the corresponding sulfonamides using molecular oxygen (O₂) and ammonia (NH₃) as respective oxygen and nitrogen sources, without the need for any additives.
