Lithium diselenide in aprotic medium - a convenient reagent for synthesis of organic diselenides

Tetrahedron, 1988
Abstract The reduction of selenium with lithium in THF in the presence of diphenylacetylene as a catalyst afforded lithium diselenide, which reacted with electrophiles giving alkyl or aryl diselenides 1 - 3 and selenides 4 , as by-products. The useful method for preparation of diselenides based on this reaction was elaborated.

Azomethine diselenides: Supramolecular structures and facile formation of a bis-oxazoline diselenide

Journal of Organometallic Chemistry, 2012
Abstract A series of N2Se2 and N2Se2O2 acyclic Schiff base diselenides ( 3 – 9 ) have been synthesized by condensation of bis( o -formylphenyl) diselenide and amines (aniline, p -bromoaniline, benzylamine, ethanolamine, 1-aminopropanol, 2-aminophenol).

On the polymorphism of niobium diselenide

Journal of the Less Common Metals, 1971
Abstract Four polymorphe of niobium diselenide have been found, viz. , 1 s -NbSe 2 , stable above 980 °C, 4 s (d)-NbSe 2 , stable between 980° and 910 °C, and the 2 s (a)- and 4 s (a)-forms stable at lower temperatures; 4 s (a)-NbSe 2 is somewhat richer in selenium than the 2 s (a)-form.

Toxicity of cadmium telluride, copper indium diselenide, and copper gallium diselenide

Progress in Photovoltaics: Research and Applications, 1999
This paper reviews recently derived toxicity data for Copper Indium Diselenide (CIS), Cadmium Gallium Diselenide (CGS) and Cadmium Telluride (CT), promising new materials on which a new generation of thin-film photovoltaic cells for generating electricity may be based. The new data deal with systemic and reproductive toxicity, acute pulmonary toxicity,

Antifriction properties of diselenides

Soviet Powder Metallurgy and Metal Ceramics, 1968
1. A study was made of the influence of temperature and environment of the coefficients of friction of natural molybdenum disulfide and synthesized molybdenum, tungsten, and niobium diselenides. 2. The maximum temperatures of effective operation of the materials investigated in various gaseous environments have been established.
