在碱性条件下，聚邻二硒代苯被硼氢化钾还原成双硒负离子后与二卤代物缩合关环，得到７个邻苯二硒型硒杂冠醚化合物，其结构经元素分析、ＭＳ、ＩＲ和~１Ｈ ＮＭＲ证实。
Under alkaline conditions, poly-o-selenobenzene was reduced to double selenium anion by potassium borohydride and then condensed with dihalogenated ring to get 7 o-selenobenzene selenonium selenium compounds. The structure of the compounds was characterized by elemental analysis, MS, IR and ~ 1H NMR confirmed.
