Organic solvents, chemicals and reagents were purchased from E. Merck, Fluka and Sigma-Aldrich. Copper(II) acetate, potassium thiocyanate, mercury(II) chloride, thionyl chloride, benzoic acid, copper(II) chloride, magnesium sulfate, 2,6-dichloroaniline, DMF, chloroform, methanol, n-hexane and p-toludine were processed without foster refinement. Triethylamine, dibutylamine, sec- butylamine, n-butylamine, isobutylamine, tert-butylamine, propylamine and isopropylamine were purified through distillation. In addition, the solvents such as alcohols, chloroform, acetone, n-hexane, dichloromethane and petroleum ether were first distilled, purified, and dried in an established manner. Finally their saturation with nitrogen, storage over molecular sieves of 4 Å and degassing was achieved.[36]
