《One-pot aerobic oxidative sulfonamidation of aromatic thiols with ammonia by a dual-functional β-MnO2 nanocatalyst》 was published in Chemical Communications (Cambridge, United Kingdom) in 2020. These research results belong to Hayashi, Eri; Yamaguchi, Yui; Kita, Yusuke; Kamata, Keigo; Hara, Michikazu. Electric Literature of C7H9NO2S The article mentions the following:
High-surface-area β-MnO2nanoparticles could act as effective heterogeneous catalysts for the one-pot oxidative sulfonamidation of various aromatic and heteroaromatic thiols to give corresponding sulfonamides ArSO2NH2 [Ar = Ph, 2-thienyl, 4-BrC6H4, etc.] using mol. oxygen and ammonia as resp. oxygen and nitrogen sources, without the need for any additives. In the part of experimental materials, we found many familiar compounds, such as 4-Methylbenzenesulfonamide(cas: 70-55-3Electric Literature of C7H9NO2S)
4-Methylbenzenesulfonamide(cas: 70-55-3) belongs to anime. Aniline, ethanolamines, and several other amines are major industrial commodities used in making rubber, dyes, pharmaceuticals, and synthetic resins and fibres and for a host of other applications. Most of the numerous methods for the preparation of amines may be broadly divided into two groups: (1) chemical reduction (replacement of oxygen with hydrogen atoms in the molecule) of members of several other classes of organic nitrogen compounds and (2) reactions of ammonia or amines with organic compounds.Electric Literature of C7H9NO2S
