Name: 4-Chlorobenzenesulfonyl chlorideIn 2022 ,《Time and Atom Economical Regio- and Chemoselective Radical Cyclization of Unactivated 1,6-Enynes Under Metal- and Oxidant-Free Conditions》 appeared in Chemistry – A European Journal. The author of the article were Mutra, Mohana Reddy; Li, Jing; Chen, Yu-Ting; Wang, Jeh-Jeng. The article conveys some information:
Authors developed time-atom economic regio- and chemoselective sulfonyl radical triggered 5-exo-dig cyclization of unactivated 1,6-enynes with sulfonyl halides under metal, additive-free reaction conditions to achieve highly substituted five-membered heterocyclic compounds I (R1 = Me, Ph, 3-O2NC6H4, etc.; R2 = Me, Ph; R3 = H, Me, t-Bu, etc.; X = N(Ts), O, NC(O)Ph, etc.). This transformation creates three new bonds, such as C-SO2, C-C, and active C-I/Br bonds. Importantly, one-pot protocols produce desired products directly from sodium sulfinates and have an addnl. advantage such as minimising chem. waste, saving time, and simplifying practical aspects compared to existing protocols.

4-Chlorobenzenesulfonyl chloride(cas: 98-60-2) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties.Name: 4-Chlorobenzenesulfonyl chloride Organochlorine compounds have wide use in many applications, though some are of profound environmental concern, with TCDD being one of the most notorious.
