Under metal catalyst-free and exogenous-oxidant-free conditions, a series of C-3 aminated imidazo[1,2-a]pyridines were synthesized by electrochemical intermolecular oxidative C-H/N-H cross-coupling. Furthermore, by using a catalytic amount of ferrocene as

In this work, we achieved a site-selective amination of 2-arylimidazoheterocycles on the C3 position using photo-induced external oxidant-free strategy. The C?N bond formation with H2 evolution was realized via the oxidative C?H/N?H coupling. This protocol may have significant implications in the late-modification of complicated drug molecules. In addition, we also used CV and DFT calculations to study the mechanism, which showed that the arene radical cation played an important role in accelerating the C?H amination process.

Several 2-arylimidazo[2,1-b]benzothiazoles (4) have been conveniently synthesized in one-pot reactions via α-tosyloxylation of enolizable ketones (1) using [hydroxy(tosyloxy)iodo]benzene 2 in acetonitrile, followed by treatment with 2-amino-6-(substituted
