《Synthesis of di(hetero)aryl sulfides by defluorinative sulfenylation of polyfluoroalkyl ketones with sodium sulfinates or arylsulfonyl chlorides》 was written by Chu, Xue-Qiang; Xie, Ting; Wang, Ya-Wen; Li, Xiang-Rui; Rao, Weidong; Xu, Haiyan; Shen, Zhi-Liang. Application of 16629-19-9 And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2020. The article conveys some information:
A facile incorporation of a privileged sulfide, naphthofurans e.g., 2-(perfluoroethyl)-3-(p-tolylthio)naphtho[1,2-b]furan framework, and a perfluoroalkyl moiety in one mol. was successfully accomplished through tandem defluorinative sulfenylation of α-perfluoroalkyl ketones e.g., 2-(Perfluorobutyl)-3,4-dihydronaphthalen-1(2H)-one with a sulfur source RS(O)ONa/RS(O)OCl (R = Ph, naphthalen-1-yl, thiophen-2-yl, etc.). The reaction presumably proceeds via a sequence involving defluorination, reductive sulfenylation, autoaromatization, and annulation, accompanied by the simultaneous cleavage of four C(sp3)-F bonds and the formation of new C-S and C-O bonds. The experimental process involved the reaction of Thiophene-2-sulfonyl chloride(cas: 16629-19-9Application of 16629-19-9)
Thiophene-2-sulfonyl chloride(cas: 16629-19-9) is a member of sulfonyl chlorides. Sulfonyl chlorides are reactive sulfonic acid derivatives similar in properties and reactivity to acid chlorides of carboxylates. The sulfonic acid group, however, is a highly hindered molecule, containing a tetrahedral configuration of substituents. Application of 16629-19-9
