β,β′-Dichlorodiethyl ether reacted with elemental selenium or tellurium, as well as with binary chalcogen mixtures (S/Se, S/Te, or Se/Te), activated in the system hydrazine hydrate-base to give oligomeric products containing oxygen and polychalcogenide fragments in the chain. Reductive cleavage of these oligomers gave rise to 3-oxapentane-1,5-dichalcogenols and their methyl derivatives. The latter were also synthesized from β,β′-dichlorodiethyl ether and the corresponding dimethyl dichalcogenides in the system hydrazine hydrate-KOH.
β,β′-二氯二乙醚与元素硒或碲以及二元钙原混合物(S/Se、S/Te 或 Se/Te)发生反应,并在水合肼基体系中活化,从而产生链中含有氧和多钙原片段的低聚物。这些低聚物的还原裂解产生了 3-氧杂戊烷-1,5-二钙原醇和它们的甲基衍生物。后者也是在水合肼-KOH 体系中由β,β′-二氯二乙醚和相应的二甲基二钙化物合成的。
