摘要: Abstract A series of naphtho[1′,2′:4,5]imidazo[1,2- a ]pyridines were synthesized smoothly from 2-arylimidazo[1,2- and alkynes involving rhodium(III)-catalyzed C–H bond functionalization. The process selected Co(OAc) 2 ·4H O as the co-catalyst for first time minimized reaction to 2 h under air atmosphere. Some products exhibited deep blue luminescence properties.
