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。

Palladium(II) complexes with benzodithia-12(18)-crown-4(6) ethers were demonstrated to have a cis-configured S2PdY2 fragment (Y = Cl, OAc). In the case of Pd(II) and benzodithia-21-crown-7 ethers, only complexes with a trans configuration of the S2PdY2 fragment form. In the case of Pd(II) and nitrobenzomonothia-15-crown-5 ether, only 2(ligand):1(Pd) complex with trans configuration of the core fragment

A series of thiaazapodands were synthesized from 4′-nitrobenzothiacrown ethers by nucleophilic regioselective opening of the macrocycle on heating with methylamine in up to 94% yield.
and also allows the use of the synthetic approach for more complex compounds. Two convenientprocedures for the synthesis of thia- and azacrown ether containing 4-nitro-1,8-naphthalimides have been developed. The first procedure is based on the amination of 1,8-naphthalic anhydride with crown-containing anilines. The second procedure includes the macrocyclization reaction of N-[1,2-bis(2-haloethox
