Several copper-catalyzed 7 -arylation reactions of imidazole have been published. The coupling of arylboronic acids with imidazole in the presence of binuclear bis-p,-hydroxy copper (11) complexes in air has been carried out at ambient temperature without the need for base <04TL7659>. A variety of A -arylimidazoles were prepared in excellent yields through the cross-coupling of arylboronic acids with imidazole in methanol or water with copper(I) chloride <04CC188>. Copper(II) oxide-coated nanoparticles were used catalytically in the Ullmann coupling of imidazole with various aryl chlorides with cesium carbonate in dimethyl sulfoxide <04CC778>.

Benzylic and allylic alcohols are oxidised to the corresponding aldehydes or ketones in the presence of copper(n) chloride/cesium carbonate as a catalyst under oxygen (Scheme 15.44). A catalytically active p-hydrojyl-bridged trinuclear copper species was isolated and its X-ray crystal structure was determined. A highly efficient oxidation of propargylic alcohols to ynones under air has been carried out in the presence of copper nanoparticles (Cu Nps) with bipyridine as a ligand (Scheme 15.45). ... 

This reaction is similar to 13-1 and, like that one, generally requires activated substrates. With unactivated substrates, side reactions predominate, though aryl methyl ethers have been prepared from unactivated chlorides by treatment with MeO in HMPA. This reaction gives better yields than 13-1 and is used more often. A good solvent is liquid ammonia. The compound NaOMe reacted with o- and p-fluoronitrobenzenes 10 times faster in NH3 at — 70°C than in MeOH. Phase-transfer catalysis has also been used. The reaction of 4-iodotoluene and 3,4-dimethylphenol, in the presence of a copper catalyst and cesium carbonate, gave the diaryl ether (Ar—O—Ar ). Alcohols were coupled with aryl halides in the presence of palladium catalysts to give the Ar—O—R ether. Nickel catalysts have also been used. ... 

The effect of bath additives on the electrocodeposition of alumina-copper has been studied. Chloride ion was found to significantly inhibit incorporation of alpha alumina in an acidic copper bath [27, 51], whereas thallium ions, cesium ions, and tetra-ethylene pentamine were promoters [25, 32].
