With Copper

In 2009, Fabris, Da tan, and coworkers [44] reported the application of copper(I) thiophen-2-carboxylate (CuTC) for the cydotrimerization of vfc-bromo(trimethyltin)olefins. The reaction gave some useful products including a pyridazine compound. [Pg.454]

Diaryl ditellurium compounds will lose one tellurium atom forming diaryl tellurium products when heated above their melting points. This conversion can be affected almost quantitatively by refluxing the diaryl ditellurium with copper powder in toluene or dioxane. [Pg.419]

6-trimethylphenyl] Tellurium A solution of 4.94 g (10 mmol) of bis[2,4,6-trimethylphenyl] ditellurium in 150 ml of toluene and 1.40 g (22 mmol) of electrolytic copper are placed in a 250-m/ flask fitted with a reflux condenser. The mixture is heated under reflux for 12h, filtered, and the filtrate is evaporated to dryness to give the pure product m.p. 123-125°. [Pg.419]

Irgolic Organo Tellurium Compounds with 2 Te —C Bonds or 1 Te = C Bond [Pg.420]


R often Me) formed by oxidative polymerization of phenols using oxygen with copper and an amine (pyridine) as catalysts. The products are thermoplastics used in engineering applications and in electrical equipment. [Pg.322]

Glass is available with good insulating properties. It is comparatively cheap and the technology of its application is well known. Glass offers excellent vacuum tightness and can be joined e.g. with copper or tungsten. [Pg.533]

Roughness has important implications in wetting applications. While the eutectic solder, SnPb, normally forms a contact angle of 15-20° with copper, it completely wets the surface of rough electroplated copper and forms a fractal spreading front [69]. [Pg.359]

Because of ammine formation, when ammonia solution is added slowly to a metal ion in solution, the hydroxide may first be precipitated and then redissolve when excess ammonia solution is added this is due to the formation of a complex ammine ion, for example with copper(II) and nickel(II) salts in aqueous solution. [Pg.218]

By their oxidising action heating with copper and concen trated sulphuric acid yields brown fumes of nitrogen dioxide. [Pg.243]

Despite its electrode potential (p. 98), very pure zinc has little or no reaction with dilute acids. If impurities are present, local electrochemical cells are set up (cf the rusting of iron. p. 398) and the zinc reacts readily evolving hydrogen. Amalgamation of zinc with mercury reduces the reactivity by giving uniformity to the surface. Very pure zinc reacts readily with dilute acids if previously coated with copper by adding copper(II) sulphate ... [Pg.417]

Aminopyridine (I) is converted by diazotisation in the presence of bromine and concentrated hydrobromic acid Into 2 broraopyridine (II) the latter upon treatment with copper powder in the presence of p-cymene yields 2 2 -dipyridyl (III). [Pg.992]

Ultrapure iodine can be obtained from the reaction of potassium iodide with copper sulfate. Several other methods of isolating the element are known. [Pg.122]

Some prapargylic halides can be converted into haloallenes by treating them with copper[I) halide and lithium halide, preferably in THF as solvent. A catalytic amount of the copper salt, which forms a soluble complex with lithium halide, is... [Pg.154]

Trichloroethanol may be used analogously. The 2,2,2-trichloroethyl (Tee) group is best removed by reduction with copper-zinc alloy in DMF at 30 °C (F. Eckstein, nucleic acid synthesis see section 4.1.1. [Pg.167]

Carbon-oxygen bonds are formed by the Ullmann reaction (- coupling of aryl halides with copper) which has been varied in alkaloid chemistry to produce diaryl ethers instead of biaryls. This is achieved by the use of CuO in basic media (T. Kametani, 1969 R.W. Dos-kotch, 1971). [Pg.294]

The oxidative coupling of toluene using Pd(OAc)2 via />-tolylmercury(II) acetate (428) forms bitolyl[384]. The aryl-aryl coupling proceeds with copper and a catalytic amount of PdCl2 in pyridine[385]. Conjugated dienes are obtained by the coupling of alkenylmercury(II) chlorides[386]. [Pg.82]

Terminal alkynes react with propargylic carbonates at room temperature to afford the alka-l, 2-dien-4-yne 14 (allenylalkyne) in good yield with catalysis by Pd(0) and Cul[5], The reaction can be explained by the transmetallation of the (7-allenylpailadium methoxide 4 with copper acetylides to form the allenyKalk-ynyl)palladium 13, which undergoes reductive elimination to form the allenyl alkyne 14. In addition to propargylic carbonates, propargylic chlorides and acetates (in the presence of ZnCb) also react with terminal alkynes to afford allenylalkynes[6], Allenylalkynes are prepared by the reaction of the alkynyl-oxiranes 15 with zinc acetylides[7]. [Pg.455]

Treating 2-bromothiazole with copper at 170°C in cumene as solvent affords the 2.2 -bisthiazole (Scheme 9) (69). The 2-halogenothiazoles can... [Pg.573]

Although It IS possible to prepare aryl chlorides and aryl bromides by electrophilic aromatic substitution it is often necessary to prepare these compounds from an aromatic amine The amine is converted to the corresponding diazonmm salt and then treated with copper(I) chloride or copper(I) bromide as appropriate... [Pg.948]

Diazotization of a primary arylamine followed by treatment of the diazo mum salt with copper(l) bromide or copper(l) chloride yields the corre spending aryl bromide or aryl chloride... [Pg.973]

Oxidation with Benedict s reagent (Section 25 19) Sugars that con tain a free hemiacetal function are called reducing sugars They react with copper(ll) sulfate in a sodium citrate/sodium carbonate buffer (Benedict s reagent) to form a red precipitate of copper(l) oxide Used as a qualitative test for reducing sugars... [Pg.1063]
