catalysis and hydrogen atom transfer to achieve the alkylation of 2H-benzothiazoles with alcohols, ethers, lactams, amides and alkane, which features broad substrate scope and excellent functional group compatibility. Notably, alcohols can be used not only as hydroxyalkylating reagents, but also as dehydroxyalkylating reagents in this regulable alkylation protocol. The previous elusive self-photocatalytic
Substituted benzothiazoles are synthesized by metal-catalyst-free three-component reactions of o-iodoaniline, quaternary ammonium salt, and sulfur powder in water with moderate-to-excellent yields up to 95%.
