Secondary benzyl halide
Web11 Oct 2024 · The reaction is also compatible for the coupling of internal alkenes, secondary benzyl halides and variously substituted arylzinc reagents. Kinetic studies reveal that the reaction proceeds with a rate-limiting single-electron-transfer process and is autocatalyzed by in-situ-generated ZnX 2. Web17 Dec 2024 · Given that hindered, secondary electrophiles are documented as challenging substrates for indole alkylation, 37 it is encouraging that a secondary benzyl halide was tolerated in this study, to give indole 4v, albeit in somewhat modest yield. Somewhat surprisingly, iodomethane was a less effective substrate in this reaction cascade and 2.5 …
