摘要

Abstract S-aryl thioacetates can be prepared by reaction of inexpensive potassium thioacetate with both electron-rich and electron-poor aryl iodides under a base-free copper/ligand catalytic system. CuI as copper source affords S-aryl thioacetates in good to excellent yields, by using 1, 10-phenanthroline as a ligand in toluene at 100 C after 24 h. Under microwave irradiation the time was drastically reduced to 2 h. Both procedures are ...
