Abstract
Lithium dialkylcopper, cuprate, is prepared in situ by treating a suspension of cuprous iodide in ether or THF with 2 equivalent of alkyllithium. Anhydrous cupric chloride is prepared by heating commercially available CuCl2·2H2O at 120°C for several hours. Cuprous oxide is prepared by heating commercially available Cu2O in vacuo at 6070°C for several hours. Copper (I) carbonyl cation is generated by treating cuprous oxide in sulfuric acid with 1 atm. of carbon monoxide. Active copper powder is prepared by reducing cupric sulfate in water with zinc powder under nitrogen gas. Copper (I) tert-butoxide is prepared by reacting anhydrous cuprous chloride with lithium tert-butoxide in THF. Copper (I) tert-butoxide is thermally stable under nitrogen and purified by sublimation at 170°C/1 mmHg. Copper (I) triflate · (benzene) 1/2 complex is prepared by heating cuprous oxide with trifluoromethanesulfonic acid anhydride in benzene at reflux. Some synthetic reactions using the copper compounds thus prepared are also described.
