A technique is described for the preparation of a wide variety of basic derivatives of linearly condensed tricyclic systems formed by two external benzene nuclei and a 7-membered central ring having 2 chalcogen atoms as hetero atoms. Derivatives of 11H-dibenzo(b,e)-1,4-dioxepin are obtained when the chalcogens are both oxygen atoms; derivatives of 11H-dibenzo(b,f)-1,4-dithiepin are obtained when the chalcogens are both sulfur atoms; derivatives of 6H-dibenz(b,e)-1,4-oxathiepin and 11H-dibenz(b,f)-1,4-oxathiepin are obtained with combinations of sulfur and oxygen atoms as chalcogens.
描述了一种技术,用于制备由两个外部苯核和一个具有2个硫族元素原子作为杂原子的7-成员中心环形成的线性紧凑三环系统的各种基本衍生物。当硫族元素均为氧原子时,得到11H-二苯并(b,e)-1,4-二氧杂环己烷的衍生物;当硫族元素均为硫原子时,得到11H-二苯并(b,f)-1,4-二硫杂环己烷的衍生物;当硫族和氧族元素的组合作为硫族元素时,得到6H-二苯并(b,e)-1,4-氧硫杂环己烷和11H-二苯并(b,f)-1,4-氧硫杂环己烷的衍生物。
