In 2019,Organic Letters included an article by Marcyk, Paul T.; Cook, Silas P.. Safety of 4-Methylbenzenesulfonamide. The article was titled 《Iron-Catalyzed Hydroamination and Hydroetherification of Unactivated Alkenes》. The information in the text is summarized as follows:
The hydrofunctionalization of alkenes, explored for over 100 years, offers the potential for a direct, atom-economical approach to value-added products. While thermodynamically favored, the kinetic barrier to such processes necessitates the use of catalysts to control selectivity and reactivity. Modern variants typically rely on noble metals that require different ligands for each class of hydrofunctionalization, thereby limiting generality. This Letter describes a general iron-based system that catalyzes the hydroamination and hydroetherification of simple unactivated olefins. In the experiment, the researchers used many compounds, for example, 4-Methylbenzenesulfonamide(cas: 70-55-3Safety of 4-Methylbenzenesulfonamide)
4-Methylbenzenesulfonamide(cas: 70-55-3) belongs to anime. The methylamines occur in small amounts in some plants. Many polyfunctional amines (i.e., those having other functional groups in the molecule) occur as alkaloids in plants—for example, mescaline, 2-(3,4,5-trimethoxyphenyl)ethylamine; the cyclic amines nicotine, atropine, morphine, and cocaine; and the quaternary salt choline, N-(2-hydroxyethyl)trimethylammonium chloride, which is present in nerve synapses and in plant and animal cells.Safety of 4-Methylbenzenesulfonamide
