Abstract: Compared with the well-known palladium-catalyzed oxidative dehydrogenation coupling reactions, similar transforms initiated by copper/oxygen have attracted more and more attention. We have investigated a novel construction of heteroaromatic imidazoACHTUNGTRENNUNG [1, 2-a] pyridines through copper (I) iodide/boron trifluoride etherate/oxygenmediated dehydrogenative reactions of aryl alkyl or alkyl alkyl ketones ...
