  摘要：

  通过过渡金属催化或 S N Ar 反应制备S -芳基黄原酸酯因其在所用条件下的进一步转化而变得复杂。相比之下，O-烷基黄原酸钾与二芳基碘盐的 S-芳基化反应在温和条件下进行，从而能够获得取代的S-芳基黄原酸。该方法表现出良好的官能团耐受性，可应用于药物分子的后期C-H功能化。由此产生的S -芳基黄原酸酯的不同转化提供了快速获得一系列与药物化学相关的有机硫化合物的途径。

  The hydrolysis and aminolysis of a series of S-substituted O-alkylxanthate esters was studied in 20% v/v aqueous methanol at 35°C. The pH-rate profiles of the hydrolyses showed water and hydroxide-ion-catalyzed reactions. The reaction of 2,4-dinitrophenyl cellulose xanthate (CelXDNP) and p-nitrobenzyl cellulose xanthate (CelXNB) with polyalanine and lysozyme produced a covalent bond between the polypeptide

• Structure-reactivity relationships in the aminolysis of O-ethyl S-aryl dithiocarbonates in aqueous solution

  The reactions of O-ethyl S-(X-phenyl) dithiocarbonates (X = p-Cl, p-Me, and p-MeO) with a series of secondary alicyclic amines and those of the same substrates and analogous derivatives (X = H, p-NO2, and 2,4-(NO2)2) with pyrrolidine are subjected to a kinetic study in water, 25.0-degrees-C, ionic strength 0.2 M (KCl). The reactions of piperidine and pyrrolidine show second-order kinetics (first order in amine) with the formation of a zwitterionic tetrahedral intermediate (T+/-) as the rate-determining step, The reactions of the other amines exhibit orders in amine different from one, compatible with the presence of an anionic intermediate (T-), resulting from a kinetically important proton transfer from T+/- to the amine. The rate of this proton transfer is faster than that of expulsion of arylthiolate from T+/- (k2) as evidenced by the estimation of these rate coefficients. The rate constants for formation of T+/- (k1) are obtained experimentally, and those for amine expulsion from T+/- (k-1) are estimated. Equations for k1 and k-1 are derived as functions of the basicity of the amine and leaving (aryl thiolate) groups. Comparison of the k-1 and k2 values found in the present reactions with those obtained in the aminolysis of aryl dithioacetates shows that substitution of Me by EtO as the ''acyl'' group of the zwitterionic tetrahedral intermediate destabilizes this species.
