    关于不对称二酰基硫化物及其与氯或溴的裂解
    摘要:
    通过使羧酸氯化物与单硫代羧酸或O-烷基-单硫代碳酸的碱金属盐反应,可以制得不对称的二酰基硫化物( 3、7 ),并对其“对称化”和热分解进行了研究。用卤素,尤其是氯进行裂解,会生成反应性很强的酰基卤化硫( 12、13、16、27、30 )。在它们的其他反应产物中,描述了先前未知的烷基或芳基酰基二硫化物或三硫化物( 18、23 ),不对称的二酰基二硫化物(21、22)和酰基二硫卤化物( 17、24 )。

  • Efficient Synthesis of 1,2,4-Dithiazolidine-3,5-diones [Dithiasuccinoyl-Amines] from Bis(chlorocarbonyl)disulfane Plus Bis(trimethylsilyl)amines

    dithiasuccinoyl (Dts)-amine, serves as a readily removable amino protecting group for building blocks used in syntheses of peptides, glycopeptides, and PNA; it is also useful as a masked isocyanate and (inversely) as a sulfurization reagent for trivalent phosphorus. Bis(chlorocarbonyl)disulfane, the two-sulfur analogue of succinyl chloride, has been envisioned as a reagent for facile single-step elaboration of the
    1,2,4-二噻唑烷-3,5-二酮杂环,也称为二硫代琥珀酰 (Dts)-胺,作为一种易于去除的氨基保护基团,用于合成肽、糖肽和 PNA 的结构单元;它也可用作掩蔽异氰酸酯和(相反)用作三价磷的硫化试剂。双(氯羰基)二硫烷是琥珀酰氯的双硫类似物,已被设想为用于轻松单步制备杂环的试剂。然而,由于所讨论的原因,双(氯羰基)二硫烷直接与伯胺反应不能产生 Dts-胺。受到有机硅化学文献中的几个先例的启发,即三甲基甲硅烷基可以作为“大质子”,成功地,已开发出通过双(氯羰基)二硫烷与双(三甲基甲硅烷基)胺反应制备 Dts-胺的高产率方法。还介绍了旨在阐明这些观察结果的机械原因的研究。

    Monothiocarbonate derivatives of diorganotellurium(IV), R2Te[SCO2R′]2, and R2TeX[SCO2R′], where R = Me, Ph; R′ = Me, i-Pr; X = Cl, Br, and I, have been prepared and characterized by vibrational and 1H, 13C, and 125Te NMR spectroscopy. Me2Te[SCO2(i-Pr)]2 (2): P21/n (No. 14) with cell parameters a = 6.942(6) Å, b = 25.599(3) Å, c = 9.404(6) Å, β = 94.48(6)°, V = 1666(1) Å3, Z = 4, R = 0.0648, Rw = 0.0624; Ph2Te[SCO2(i-Pr)]2 (4): P21/n (No. 14) with a = 12.360(4) Å, b = 12.277(3) Å, c = 15.066(3) Å, β = 102.82(2)°, V = 2229.1(9) Å3, Z = 4, R = 0.0368, Rw = 0.0312; Me2TeCl[SCO2Me] (5); P21/c (No. 14) with a = 5.193(2) Å, b = 18.118(4) Å, c = 9.613(5) Å, β = 91.31(6)°, V = 904.2(6) Å3, Z = 4, R = 0.0396, Rw = 0.0361; and Me2TeBr[SCO2(i-Pr)] (8): P21/n (No. 14) with a = 11.701(2) Å, b = 6.250(2) Å, c = 16.152(2) Å, β = 98.43(1)°, V = 1168.4(4) Å3, Z = 4, R = 0.0369, Rw = 0.0325. In all molecules, the immediate environment about tellurium is that of the saw-horse structure in which the lone pair is assumed to be stereochemically active and occupying an equatorial position in a distorted trigonal bipyramid. In 2 and 5, the terminal oxygen atoms are oriented toward tellurium, whereas in 4, one O(i-Pr) group is oriented toward tellurium, as it is in 8. In the latter cases, the terminal oxygen atoms act as weak bridges to form a pseudo dimeric species in 4 and a pseudo polymer in 8. Supramolecular interactions in 2 and 5 lead to a sulfur-bridged dimer in the former and a chlorine-bridged polymer in the latter. Key words: structure, tellurium, dimethyl, diphenyl, monothiocarbonates.
