Oligomeric trimethylene dichalcogenides and the corresponding 1,2-dichalcogenolanes having both similar and different chalcogen atoms in the molecule were synthesized by reactions of 1-bromo-3-chloropropanes with two elemental chalcogens (S, Se; S, Te; Se, Te) activated by the system hydrazine hydrate-alkali. Reductive cleavage of the oligomeric products in the system hydrazine hydrate-alkali, followed by alkylation with methyl iodide or ethyl bromide gave 1,3-bis(alkylchalcogeno)propanes. The latter were also obtained from the corresponding dialkyl dichalcogenides and 1-bromo-3-chloropropane in the alkaline reducing system.

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 N2H 4?H2O/KOH system. Mass spectra of the synthesized low molecular weight organotellurium compounds are considered. Pleiades Publishing, Inc., 2006.
