Solvent-free palladium-catalyzed direct arylation of heteroaromatics with aryl bromides

Solvent is one of the major sources of waste in the course of catalyzed direct arylations. Some palladium-catalyzed direct arylations of heteroaromatics can be advantageously performed without any solvent. In the presence of palladium catalysts (1 mol%) and potassium acetate as the base, the direct 5-arylation of some thiazoles, thiophenes, furans, or pyrroles with aryl bromides as coupling partners proceeds highly regioselectively and in moderate to high yields. However, the use of these solvent-free conditions is limited to electron-deficient aryl bromides. Copyright
Ligand-free palladium-catalyzed direct arylation of thiazoles at low catalyst loadings

Ligand-free Pd(OAc)2 was found to catalyze very efficiently the direct arylation of thiazole derivatives under very low catalyst concentration. By using activated aryl bromides, the reaction can be performed employing as little as 0.1-0.001 mol
