A synthesis of oligomeric substance of thiocol type, the poly(trimethyleneditelluride), from 1-bromo-3-chloropropane and elemental tellurium is performed using a hydrazine hydrate-alkali system. Reductive splitting of the tellurocol followed by alkylation with methyl iodide give rise to preparation of bis(methyltelluro)propane, which was synthesized also from dimethyltelluride and 1,3-dihalopropanes using the (N2H4H2O)-H-./KOH system. Mass spectra of the synthesized low molecular weight organotellurium compounds are considered.

HgTe and HgCdTe (MCT) layers have been grown by organometallic vapor phase epitaxy at lowtemperature by usingmethylallyltelluride (MATe), dimethylcadmium (DMCd), and elemental mercury. Use of MATe enabled the growth of layers in the 250–320 °C temperature range, which is 50 °C lower than the growthtemperature when diisopropyltelluride is used as the tellurium alkyl, for the same growth rate.
