Based on the strategy of the development of phosphine-free palladium-catalyzeddirect C–H arylation, a series of camphyl-based α-diimine palladium complexes bearing sterically bulky substituents were synthesized and characterized. The palladium complexes were applied for the cross-coupling of thiazole derivatives with arylbromides. The effect of the sterically bulky substituent on the N-aryl moiety
Direct C-H bond (Hetero)arylation of thiazole derivatives at 5-position catalyzed by N-heterocyclic carbene palladium complexes at low catalyst loadings under aerobic conditions
synthesis of 5-(hetero)arylated thiazole derivatives via an N-heterocyclic carbene palladium (Pd-NHC) complex catalyzed directC-Harylation reaction. Utilization of this methodology, the arylation of substituted thiazoles with (hetero)aryl bromides efficiently proceeded at low catalyst loading (0.1–0.05 mol%) and under aerobic conditions. A variety of (hetero)aryl bromides, even some strongly deactivated
