  A Mechanism for the Oxidation of Glutathione to Glutathione Disulfide with Organotellurium(IV) and Organoselenium(IV) Compounds. A Stepwise Process with Implications for Photodynamic Therapy and Other Oxidative Chemotherapy

  摘要：

  The reactions of telluroxides or their hydrates 3-5 with glutathione to give telluropyrylium dyes 1, 2 or diphenyl telluride, respectively, and glutathione disulfide have at least two discrete steps. A fast reaction, which is first-order in both substrate and glutathione, is observed with second-order rate constants of 2.30 x 10(7) L mol(-1) s(-1) at 285.4 K for 3, 1.66 x 10(7) L mol(-1) s(-1) at 293.2 K for 4, and 5.2 x 10(6) L mol(-1) s(-1) at 285.5 K for 5. This reaction is followed by a slower reaction, which is first-order in both substrate and glutathione, with second-order rate constants of 2.65 x 10(5) L mol(-1) s(-1) at 293.5 K for 3, 3.34 x 10(5) L mol(-1) s(-1) at 293.2 K for 4, and 7.64 x 10(3) L mol(-1) s(-1) at 285.5 K for 5. The slow reaction is accompanied by the generation of the corresponding tellurium-(II) compound. Diphenyl selenoxide hydrate (6) displays similar behavior, although the rate constants associated with the fast (2.26 x 10(2) L mol(-1) s(-1)) and slow (6.62 x 10(1) L mol(-1) s(-1)) reactions are many orders-of-magnitude less than observed for the tellurium analogues.

  Diorganotellurium(IV) bis(fluorocarboxylates)[R2Te(OCOR')2] [R = Me, Ph,p-MeOC6H4 and p-EtOC6H4; R' = CF3, C2F5, C3F7] have been prepared by the interaction of R2Te(OMe)2 with fluorocarboxylic acids (R'COOH). Identical products were obtained by the metathetical reaction of R2TeCl2 with silver salts of the fluorocarboxylic acids in 1:2 molar ratios. However, when the reaction proceeded in a 1:1 molar ratio, the product

  The present invention relates to the use of telluroxides as mild and selective oxidizing agents serving to oxidize certain functions, notably >C.dbd.S groups, in the presence of other relatively easily oxidized functions which remain unaffected; telluroxides of interest as oxidizing agents include, for example, compounds of the formula: ##STR1## wherein R and R.sup.1, which may be the same or different, each represent an optionally substituted aryl or heterocyclic group; or R and R.sup.1 together with the tellurium atom therebetween represent a heterocyclic ring, which may contain one or more further heteroatoms, and which may carry substituents and/or fused aromatic rings.

  本发明涉及碲氧化物作为温和且选择性的氧化剂的用途，用于氧化特定功能，特别是>C.dbd.S基团，在其他相对容易被氧化的功能存在的情况下保持不受影响；作为氧化剂感兴趣的碲氧化物包括例如下式的化合物：##STR1## 其中R和R.sup.1，可以相同也可以不同，分别代表可选择地取代的芳基或杂环基团；或者R和R.sup.1与其之间的碲原子一起代表一个杂环环，该环可以含有一个或多个进一步的杂原子，并且可以携带取代基和/或融合的芳香环。

  The metal-free oxidation of sulfides to sulfones using sodium bromate (NaBrO3) in [bmim]HSO4:H2O (3:1, v/v) at 80 °C is reported. Phenylalkyl, phenylbenzyl, diaryl and heteroaryl sulfides were transformed to the corresponding sulfones. Aryl tellurides and phosphines were oxidised to the corresponding telluroxides and phosphine oxides. All the reactions proceeded smoothly and gave high yields in 20–55
