Laha, Joydev K.;Gupta, Pankaj research published ã€?Sulfoxylate Anion Radical-Induced Aryl Radical Generation and Intramolecular Arylation for the Synthesis of Biarylsultamsã€? the research content is summarized as follows. A green and practically useful synthetic protocol to access diverse six- and seven-membered biarylsultams I (R = H, Me, Ph; R¹ = H, OMe, OPh, Me; R² = H; R¹R² = -CH=CH-CH=CH-; R³ = H, Me, Cl, OCF₃, etc.; R⁴ = H, Me), and e.g., II, especially with a free NH group including demonstration of a gram-scale synthesis was reported. The sulfoxylate anion radical (SO₂^{-â€?/sup>), generated in situ from the reagents rongalite or sodium dithionite (Na₂S₂O₄), was found to be the key single electron transfer agent forming aryl radicals from aryl halides, e.g., 2-bromo-N-phenylbenzene-1-sulfonamide which upon intramol. arylation gives biarylsultams I, and e.g., II, with good to excellent yields. The approach features generation of aryl radicals that remained under-explored, use of a cheap and readily available industrial reagents, and transition metal-free, mild, and green reaction conditions.}

Laha, Joydev K.;Gulati, Upma;Saima;Schulte, Tim;Breugst, Martin research published ã€?pH-Controlled Intramolecular Decarboxylative Cyclization of Biarylacetic Acids: Implication on Umpolung Reactivity of Aroyl Radicalsã€? the research content is summarized as follows. A simple approach for the intramol. aroylation of electron-rich arenes 2-RC₆H₄CH₂C(O)OH (R = Ph, 2,5-dimethylphenyl, naphthalen-2-yl, etc.) under mild conditions has been developed. A pH-controlled polarity umpolung strategy can be used to synthesize different fluorenones I (R¹ = H, Me, OMe, F, Cl, CF₃; R² = H, OMe, CF₃, F, etc.; R¹R² = – CH:CHCH:CH-; R³ = H, Me, OMe, Cl; R⁴ = F, CF₃), which are important building blocks for biol. applications. Unlike previous acylation reactions involving nucleophilic aroyl radicals, this approach likely relies on in situ generated electrophilic aroyl radicals. Detailed mechanistic and computational investigations provide detailed insights into the reaction mechanism and support the hypothesis of a pH-mediated umpolung.
