Ru(II)-Catalyzed C7 Trifluoromethylthiolation and Thioarylation of Indolines Using Bench-Stable Reagents

The Journal of Organic Chemistry, Год журнала: 2024, Номер 89(21), С. 15893 - 15900

Опубликована: Окт. 16, 2024

A Ru(II)-catalyzed C(sp2)-H trifluoromethylthiolation and thioarylation of indolines using bench-stable reagents have been explored. Diversely substituted were functionalized at C7 position in good to excellent yields. Radical quenching, deuterium labeling, KIE, reaction order determination experiments performed support the proposed pathway. Gram-scale synthesis post-transformation synthesized products also carried out demonstrate applicability developed catalytic protocol.

Visible‐Light‐Enabled Regioselective C−H alkylation and alkenylation of 2‐Aryl Heterocycles using Dual Catalysis

Advanced Synthesis & Catalysis, Год журнала: 2024, Номер unknown

Опубликована: Дек. 17, 2024

Abstract Visible light‐induced site‐selective C−H alkylation and alkenylation of 2‐aryl heteroarenes with maleimides at room temperature via dual catalysis in an aqueous medium has been disclosed. This operationally simple mild approach enables the selective formation products up to 92% yield under silver‐free conditions excellent substrate scope. For mechanistic examination, KIE, H/D labeling experiments, light on‐off quantum measurements were carried out. Moreover, present for is suitable scalable synthesis.
