Cu(OAc)2/Pyrimidines-Catalyzed Cross-coupling Reactions of Aryl Iodides and Activated Aryl Bromides with Alkynes under Aerobic, Solvent-free and Palladium-free Conditions

Excellent results have been achieved in the Cu(OAc)2‐catalyzed Sonogashira cross‐couplings of aryl iodides and activated aryl bromides utilizing TBAF (tetrabutylammonium fluoride) as the base and 4,6‐dimethoxypyrimidin‐2‐amine as the ligand. It is noteworthy that the reaction is conducted under aero...
