Choudhuri, Khokan; Maiti, Saikat; Mal, Prasenjit published the artcile< Iodine(III) Enabled Dehydrogenative Aryl C-S Coupling by in situ Generated Sulfenium Ion>, Related Products of 576-83-0, the main research area is diaryl sulfide preparation; thiol arene phenyliodo diacetate dehydrogenative coupling reaction; aryl sulfinyl arene preparation; arene thiol phenyliodo diacetate sulfoxidation.
An umpolung based one pot and direct C-S coupling approach under metal free and mild condition were described. Electrophile sulfenium ions were generated in situ from thiols RSH (R = Ph, Et, 4-nitrophenyl, 3-chlorophenyl, etc.) using iodine(III) reagent PhI(OAc)2 (PIDA) and subsequently used for aromatic electrophilic substitution (EArS) to synthesize diaryl sulfides R1SR (R1 = 2,4,6-trimethylphenyl, 4-methoxyphenyl, 2,4-dimethylphenyl, etc.). Also by using of appropriate amount of PIDA, cascaded synthesis of C-S and S=O bonds led to aryl sulfinyl arenes R1S(O)R in one pot. Covalent self-sorting or competitive experiments further confirmed the involvement of sulfenium ion in the EArS.
