Abstract

N-lithio-2,2,6,6-tetramethylpiperidine [Li(tmp)] reacts with AlX3 (X = Cl, Br) in Et2O/n-hexane soln. to generate of substitution and ether cleavage products, [(tmp)Al(X)(m-OEt)]2 (X = Cl, Br). However, when the reaction is allowed to proceed in n-hexane alone, an almost quant. yield of (tmp)2AlX (X = Cl, Br, I) is obtained. According to 27Al NMR, mass spectroscopy, cryoscopy, and x-ray crystal structure detns., these compds. are monomeric in the solid state, in soln., and in gas phase. (Tmp)2AlBr reacts with AgBF4 yielding the fluoride-bridged dimer [(tmp)2AlF]2 as shown by x-ray crystal structure detn. [on SciFinder (R)]

Aluminium

Aluminium (aluminum in North American English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals; about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, nonmagnetic and ductile.

Spectroscopy

Spectroscopy is the field of study that measures and interprets the electromagnetic spectra that result from the interaction between electromagnetic radiation and matter as a function of the wavelength or frequency of the radiation. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory (LIGO).

Aluminium chloride

Aluminium chloride, also known as aluminium trichloride, is an inorganic compound with the formula . It forms a hexahydrate with the formula , containing six water molecules of hydration. Both the anhydrous form and the hexahydrate are colourless crystals, but samples are often contaminated with iron(III) chloride, giving them a yellow colour. The anhydrous form is important commercially. It has a low melting and boiling point. It is mainly produced and consumed in the production of aluminium metal, but large amounts are also used in other areas of the chemical industry.
