The basic study was performed on copper complexes with N,N,N, N1-tetramethylethane-1,2-diamine (TMED), which were known to be very effective oxidative coupling catalysts (7,12). From our first kinetic studies it appeared that binuclear copper complexes are the active species as in some copper-containing enzymes. By applying the very strongly chelating TMED we were able to isolate crystals of the catalyst and to determine its structure by X-ray diffraction (13). Figure 1 shows this structure for the TMED complex of basic copper chloride Cu(0H)Cl prepared from CuCl by oxidation in moist pyridine.

During a series of basic experiments in homogeneous catalysis at the M. W. Kellogg Laboratory, it was discovered that ethylene could be made to react with an aqueous solution of certain metal halides to give 1,2-dichloroethane at moderate temperatures and pressures e,g.y 300°F., 150 p.s.i.g.). The reaction appears to occur between complexed ethylene and the metal halide. For example using copper chloride, ethylene complexed with cuprous chloride is believed to react with cupric chloride to produce dichloroethane. The over-all reaction can be written simply as ... 

In the present system with the copper-2% zinc electrodes, all three processes of protein adsorption, charge transfer, and Faradaic oxidations and reductions are possible. The peaks observed in the anodic and cathodic processes are related, respectively, to oxidations and reductions of the electrode. Copper oxides, chlorides, basic chlorides, phosphates, etc., as well as zinc products, are probable compounds for these electrochemical reactions. Increased Faradaic processes and charge transfer processes with protein solutions are factors for increasing the j-U profiles at U s less than +0.3 V. Since the sweep rate is a constant here, the capacitance of the double layer must increase for the protein solutions, if the increase in j is not all due to Faradaic processes One analog of the electrical double layer capacitance incorporates three capacitors in series (44). Hence...

Copper exposed to industrial atmospheres forms a protective green-colored corrosion product called a patina, composed mostly of basic copper sulfate, CuS04 3Cu(0H)2. a copper-covered church steeple on the outskirts of a town may develop such a green patina on the side facing prevailing winds from the city, but remain reddish-brown on the opposite side, where sulfuric acid is less readily available. Near the seacoast, a similar patina forms, composed in part of basic copper chloride. 

Van der Meijden [30] also demonstrated that nucleation of basic copper chloride is not promoted at the surface of siUca or alumina, and that the basic copper chloride is thus not deposited onto the surface of the support. It can be expected that the pH of a copper(II) chloride solution rises in volume elements where the liquid contacts the alumina. The local growth of the pH level will lead to nucleation of...
