the synthesis of nitrobenzomonothia-15-crown-5 ether. Nitro derivatives of benzodithiacrown ethers were tested as reagents for extraction of palladium(II), platinum(IV), and rhodium(III) from hydrochloric acid solutions. Extraction of PdII salts was found to be highly selective compared to that of PtIV and RhIII salts. Benzodithia-15-crown-5 ether is the most efficient extractant for palladium(II)
1,2-双(2-卤代乙氧基)-4-硝基苯与无环α,ω-(氧杂)链烷二硫醇在碱金属碳酸盐存在下的缩合反应产生了一系列具有不同大小大环的硝基苯并二噻冠醚。通过 X 射线衍射确定了三种醚的结构。开发了一种合成硝基苯并单硫醚-15-冠-5醚的新方法。苯并二噻冠醚的硝基衍生物被测试作为从盐酸溶液中提取钯 (II)、铂 (IV) 和铑 (III) 的试剂。与 PtIV 和 RhIII 盐相比,PdII 盐的提取具有高度选择性。Benzodithia-15-crown-5 醚是钯 (II) 的最有效萃取剂。
