Aluminium telluride

Hydrogen telluride is prepared in situ by hydrolysis of aluminium telluride. 

Organyl tellurols are very unstable compounds owing to their extreme sensitivity to oxygen, giving the corresponding ditellurides. The first short-chain alkyltellurols (C1-C4) have been isolated as yellow liquids with an obnoxious odour, from the reaction of aluminium telluride and hydrogen telluride, respectively, with alcohols and aUcyl bromides. Aryltellurols seem not to have been isolated. As shown in Sections 3.1.3.2 and 3.2.2, aryl tellurolates are... 

Hydrogen telluride, H2Te, generated in situ by the hydrolysis of aluminium telluride, reduces aldehydes and ketones to the corresponding alcohols. In the presence of deuterium oxide, deuterated derivatives are formed. 

Die nachstehende Arbeitsvorschrift zeigt die Verwendung von Aluminium-tellurid bei der reduktiven Aminierung von Carbonyl-Verbindungen1. 

The ring system embodied in these cyclic derivatives is produced by condensing aluminium telluride with ae-pentamethylene dibromide ... 

Hydrogen telluride (H2Te), prepared in situ from aluminium telluride Al2Te3 and water, reduces enamines to the corresponding amines. The presence of water, however,... 

The original synthesis of diethyl teUnride by Wohler was carried out by treating potassium telluride with ethyl sulfate. The preparation of potassium telluride was rather inconvenient and involved the reduction of elemental tellurium by heating the element at red heat with potassium-hydrogen D-tartrate. An early report of Natta demonstrated that the treatment of aluminium telluride by alcohols or ethers at 250-300 °C is also a promising route to diorganyl tellurides.

When aluminium is heated with tellurium, solid aluminium telluride, Al2Te3, is formed. If this is treated with chilled dilute hydrochloric acid, a gaseous hydride of tellurium with a revolting smell is evolved. What is the formula of the hydride, and what is the shape of the molecule ...
