Kotla, Siva K. Reddy published the artcileRhodium(III)-catalyzed double C-H activation: a straightforward approach to fused imidazo[1,2-a]pyridines from internal alkynes, Safety of 2-(4-Bromophenyl)-6-methylimidazo[1,2-a]pyridine, the main research area is polycyclic imidazopyridine preparation; rhodium catalyst oxidative coupling imidazopyridine internal alkyne.
The Rh(III)-catalyzed oxidative coupling of 2-arylimidazopyridines with internal alkynes via double C-H activation has been described. This approach provides straightforward access to highly functionalized polycyclic imidazopyridines in good to excellent yields. E.g., in presence of [Cp*RhCl2]2, Cu(OAc)2, and Cs2CO3, oxidative coupling of 2-arylimidazo[1,2-a]pyridine (I) with PhCCPh gave 85% 5,6-diphenylnaphtho[1′,2′:4,5]imidazo[1,2-a]pyridine (II).
