Popis: Methods of synthesis of compounds MeY(CH2Y)nMe (Y=S, Se, Te; n = 1–3) containing several identical or different chalcogen atoms are suggested. The methods are based on the reactions of dichloromethane with elemental chalcogens (Y2−) and dimethyl dichalcogenides (MeY−) activated in the system hydrazine hydrate-alkali. The effect of the chalcogen on the reactivity toward dichloromethane is qualitatively assessed. With elemental tellurium in the system hydrazine hydrate-alkali, reduction of one chlorine atom in dichloromethane and formation of methyltellanyl derivatives are observed.
