The synthesis of novel chelating palladium complexes containing pyridine/pyrimidine hydroxyalkyl di-functionalized N-heterocyclic carbenes (NHCs) via direct metallation of the precursor imidazolium salts is presented. The structure has been characterized unambiguously by X-ray single crystal analysis. Catalytic activity investigation showed that the complexes catalyse the direct C-H bond arylation of (benzo)oxazoles efficiently when using tBuOLi as base and DMF as solvent.

Not so challenging after all! The first general examples of the direct arylation of heteroarenes by using challenging aryl mesylates as electrophiles are disclosed. These easy reaction conditions also allow the functionalization of other heterocycles, such as caffeine, triazole and benzathiazole (see scheme). Copyright
