I found the field of Chemistry very interesting. Saw the article Site-Selective C-H Functionalization-Sulfination Sequence to Access Aryl Sulfonamides published in 2020. Safety of 1,4-Dioxa-8-azaspiro[4.5]decane, Reprint Addresses Ritter, T (corresponding author), Max Planck Inst Kohlenforsch, D-45470 Mulheim, Germany.. The CAS is 177-11-7. Through research, I have a further understanding and discovery of 1,4-Dioxa-8-azaspiro[4.5]decane
Aryl sulfinates are precursors to a diverse number of sulfonyl-derived arenes, which are common motifs in pharmaceuticals and agrochemicals. Here, we report a site-selective two-step C-H sulfination sequence via aryl sulfonium salts to access aryl sulfonamides. Combined with site-selective aromatic thianthrenation, an operationally simple one-pot palladium-catalyzed protocol introduces the sulfonyl group using sodium hydroxymethylsulfinate (Rongalite) as a source of SO22-. The hydroxymethyl sulfone intermediate generated from the catalytic process can be employed as a synthetic handle to deliver a variety of sulfonyl-containing compounds.
