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.
