General Description

Dimethyl telluride is a chemical compound with the formula (CH3)2Te. It is a colorless, flammable liquid with a garlic-like odor. Dimethyl telluride is a naturally occurring compound and is produced by certain anaerobic bacteria as a metabolic byproduct. It is also a byproduct of the industrial process of producing trimethylbismuth. Dimethyl telluride is highly toxic and exposure to the compound can cause severe health effects, including respiratory irritation, nausea, and malaise. In addition, it is known to have a pungent odor, detectable at very low concentrations. Due to its toxicity and unpleasant odor, dimethyl telluride is considered a hazardous substance and must be handled with caution.

Reactions of 1,2-dihaloethanes with chalcogenide anions

Reactions of 1,2-dihaloethanes with chalcogenide anions generated from elemental chalcogens and dimethylchalcogens were performed in the hydrazine hydrate-KOH system. The use of anions Se x 2- and Te x 2- (x = 1-4) resulted in ethylene evolution and chalcogen regeneration (or in increased x value in an anion). Oligomers of Thiokol type formed only in the reaction of the 1,2-dichloroethane with a mixture of potassium disulfide and diselenide. The reductive cleavage of oligomers obtained in the hydrazine hydrate-KOH system followed by methylation led to the formation of 1,2-bis(methylthio)ethane, 1-methylseleno-2- methylthioethane, and 1,2-bis(methylseleno)ethane. The features of substitution with chalcogenide anions in vicinal dihalides are discussed. Mass spectra of compounds obtained were measured and analyzed. Pleiades Publishing, Inc. 2006.

Reaction of 1,1-dichloroethane with tellurium in the system hydrazine hydrate-potassium hydroxide

The reaction of 1,1-dichloroethane with tellurium in the system hydrazine hydrate-potassium hydroxide gave ethyltellanyl derivatives as a result of replacement of one chlorine atom in the substrate by tellurium, and of the other, by hydrogen. Probable mechanisms of reduction of the C-Cl bond and mass spectra of the products were considered. The mass spectra of ditelluroacetals revealed unusual rearrangement of the molecular ion, leading to the formation of Te-Te and new C-C bond.
