recommendations! Published in 2024 at "Asian Journal of Organic Chemistry"

DOI: 10.1002/ajoc.202400484

Abstract: A TEMPO‐oxidized method has been developed for the synthesis of bis(indolyl)‐methane derivatives by the cross‐dehydrogenative coupling between C(sp3)–H of para‐cresol derivatives and C(sp2)‐H of indoles in moderate yields under aqueous conditions. This approach has significant… read more here.
