Copper dichloride

The addition of trichloro- ortetrachloroethylene to aluminium components in dry cleaning equipments is responsible for many accidents. The effect of the carbon tetrachloride/methanol mixture in the 1/9 proportion of aluminium, magnesium or zinc causes the dissolution of these metals, whose exothermicity makes the interaction dangerous. There is a period of induction with zinc, which is cancelled out when copper dichloride, mercury dichloride or chromium tribromide is present. 

Copper dichloride bisDMSO Cu(DMSO)2Cl2 (DMSO = dimethylsulfoxide) consists of chains of roughly square planar coordinated copper with the two chloride ions and the two organic molecules in trans positions, and the chloride from an adjacent molecnle semicoordinated in an axial site (see Fignre 17). Adjacent copper sites are related by a 2 axis. 

Oxidative removal of the iron tricarbonyl group can be achieved using iron trichloride, copper dichloride, CAN, hydrogen peroxide under basic conditions, 3-chloroperbenzoic acid, or TMANO. The latter oxidant is frequently the reagent of choice. Depending on the reagent, decomplexation may occur with or without concomitant transformation (Scheme 128). It is important to note that no racemization of optically active compounds is detected upon... 

Consider the case of cupric chloride. Under many circumstances of a general nature, such as reactions using solutions of the compound, the name cupric chloride or, better still, copper dichloride suffices. If referring especially to the hydrated solid salt, either cupric chloride dihydrate or copper dichloride dihydrate is used. The full structure of the crystalline hydrated chloride is known, and if matters involving this structure were being dealt with, then the full name should be given as frans-copper dichloride dihydrate H20 Cl... 

Adducts of the l,2-dithiole-3-thione with silver nitrate and copper dichloride have been described, and for various l,2-dithiole-3-thiones, adducts containing iron, cobalt, nickel, and copper have been studied in more detail. The ligands (L) used are either unsubstituted l,2-dithiole-3-thione or its methyl- or aryl-substituted derivatives. If X represents a halogen atom, the following types of coordination compounds have been characterized CuXLj and CuXLa, FeXjLj, CoXaL, and NiX Lj. Complexes of titanium(III), tin(IV), antimony(III) and (V), and bismuth(III) have also been studied. ... 

In the benzoylation of anisole with BC, the copper(II) triflate/[bmim] [BFJ is recycled three times after washing with diethyl ether, affording the methoxy-substituted BPs in 86%, 79%, and 65% yield with an ortho/para ratio of 0.04 for all runs. The lowering of the catalyst efficiency is assumed to be due to the production of hydrogen chloride, possibly leading to the formation of an increasing amount of copper dichloride, which is inactive under these conditions.

A particularly active system was observed when mixing copper dichloride with phenylhydrazine in various organic solvents and water [49c]. Under optimum conditions, the yield reaches up to 40% per oxidized phenylhydrazine with the copper salt acting as a catalyst. The yield of products may correspond, for example, to forty redox cycles per mole of Cu salt with one portion of the reducing agent, and even several hundred cycles, if new portions of phenyl hydrazine are added after the previous hydrazine has been oxidized.

Benzene can be oxidative-cationically polymerized to brown or black products with iron chloride, aluminum trichloride/copper dichloride, etc. at mild temperatures. The insoluble material can be compressed at high pressures into mold inserts.

When metallic zinc is introduced into a solution of copper dichloride, the green colour of the solution slowly fades, and a red layer of copper is deposited on the zinc. The zinc has evidently displaced the copper from the solution of its chloride ... 

Similarly, tin displaces copper from copper dichloride solution, while zinc displaces tin from tin dichloride solution. From such experiments, the metals can again be placed in a series, with those on die left displacing those on the right from their compoimds in solution ... 

A second example is provided by ammonium compounds, e.g. ammonimn chloride, NH4CI. These are very similar to alkali metal compounds. Indeed, ammonium compounds and potassium compounds often form mixed crystals with each other. Furthermore, electrolysis of ammonimn chloride solution with a mercury cathode at 0 °C gives a grey mass that is similar in character to sodimn or potassimn amalgam. Thus, it reduces copper dichloride solution to copper, zinc chloride to zinc, etc. On warming, it decomposes into ammonia and hydrogen in the proportions required by the equation...
