Copper (II) chloride, also known as cupric chloride, is an inorganic compound with the chemical formula Cu Cl 2. The monoclinic yellowish-brown anhydrous form slowly absorbs moisture to form the orthorhombic blue-green dihydrate CuCl2·2H2O, with two water molecules of hydration.
Wacker process. The Wacker process or the Hoechst-Wacker process (named after the chemical companies of the same name) refers to the oxidation of ethylene to acetaldehyde in the presence of palladium (II) chloride and copper (II) chloride as the catalyst. [1] This chemical reaction was one of the first homogeneous catalysis with organopalladium ...
The reaction is usually initiated by copper(II) chloride (CuCl 2), which is the most common catalyst in the production of 1,2-dichloroethane.In some cases, CuCl 2 is supported on silica in presence of KCl, LaCl 3, or AlCl 3 as cocatalysts.
Copper–chlorine cycle. The copper – chlorine cycle (Cu–Cl cycle) is a four-step thermochemical cycle for the production of hydrogen. The Cu–Cl cycle is a hybrid process that employs both thermochemical and electrolysis steps. It has a maximum temperature requirement of about 530 degrees Celsius. [1]
RSC ontology ID. RXNO:0000098. The Glaser coupling is a type of coupling reaction. It is by far one of the oldest coupling reactions and is based on copper compounds like copper (I) chloride or copper (I) bromide and an additional oxidant like air. The base used in the original research paper is ammonia and the solvent is water or an alcohol.
IR absorption spectrum of copper (I) chloride. Copper (I) chloride, commonly called cuprous chloride, is the lower chloride of copper, with the formula CuCl. The substance is a white solid sparingly soluble in water, but very soluble in concentrated hydrochloric acid. Impure samples appear green due to the presence of copper (II) chloride (CuCl 2).
This results in a combination of copper oxide and pure copper nanoparticle clusters, depending on the method used. A more modern synthesis utilizes copper(II) chloride in a room temperature reaction with sodium citrate or myristic acid in an aqueous solution containing sodium formaldehyde sulfoxylate to obtain a pure copper nanoparticle powder.

In the original paper describing this reaction, methylmagnesium bromide is reacted with isophorone with and without 1 mole percent of added copper(I) chloride (see figure). [10] Without added salt the main products are alcohol B (42%) from nucleophilic addition to the carbonyl group and diene C (48%) as its dehydration reaction product.
