  In order to obtain information concerning the reaction mechanism of the pyrolysis of sulfonium ylides bearing a substituted phenyl group on the 2-position in the S-ethyl group of ethylphenylsulfonium ylide, (2-phenylethyl)phenylsulfonium bis(methoxycarbonyl)methylide (1) and dicyanomethylide (2) were subjected to pyrolysis in benzene. The reaction rates of 1 and 2 at 140 °C were 6.0- and 3.2-times faster than those of ethylphenylsulfonium bis(methoxycarbonyl)methylide and dicyanomethylide, respectively. The activation parameters for 1 were ΔH‡ = 125 kJ mol−1 and ΔS‡ = −3.8 J K−1 mol−1, while those for 2 were ΔH‡ = 124 kJ mol−1 and ΔS‡ = −2.5 J K−1 mol−1. Substituent effects on the β-phenyl groups in 1 and 2 afforded positive Hammett ρ-values: ρ = 0.49 (γ = 0.997) and ρ = 0.26 (γ = 0.993), respectively.From the obtained results, it was suggested that the pyrolysis proceeds through essentially a concerted intramolecular cis-elimination inclined toward a slightly carbanion-like type from an E1-like type by introducing a phenyl substituent at the 2-position of the ethyl group in the ethylphenylsulfonium ylide.

  为了获取有关乙基苯基亚磺酸乙酯中乙基的2-位上带有取代苯基的磺酸亚磺酸分解反应机理的信息，将（2-苯乙基）苯基亚磺酸双（甲氧基羰基）甲亚基（1）和双氰基甲亚基（2）在苯中进行分解。在140°C时，1和2的反应速率分别比乙基苯基亚磺酸双（甲氧基羰基）甲亚基和双氰基甲亚基快6.0倍和3.2倍。1的活化参数为ΔH‡ = 125 kJ mol−1，ΔS‡ = -3.8 J K−1 mol−1，而2的活化参数为ΔH‡ = 124 kJ mol−1，ΔS‡ = -2.5 J K−1 mol−1。1和2中β-苯基的取代效应提供了正的Hammett ρ值：ρ = 0.49（γ = 0.997）和ρ = 0.26（γ = 0.993）。从得到的结果可以看出，通过在乙基苯基亚磺酸乙的乙基的2-位引入苯基取代基，基本上是通过倾向于稍微类似于碳负离子的顺式消除过程，从而类似于E1型反应。

  Selective mono- and bis-sulfenylation of active methylene groups with a variety of disulfides at an ambient temperature is reported. Sulfenylation is promoted by iodine as a catalyst and sulfenyl iodides as intermediates, under metal-free conditions. The method is greener in terms of solvent selection and the use of less hazardous DMSO as an oxidant. The procedure is highly efficient with readily available

  据报道，在环境温度下，活性亚甲基与多种二硫化物的选择性单-和双-亚磺酰化反应。在无金属条件下，以碘为催化剂，以亚硫基碘为中间体，可促进亚磺酰化。该方法在溶剂选择和使用危害较小的 DMSO 作为氧化剂方面更环保。该程序非常有效，使用容易获得的起始材料，并提供良好的收率。

  日期：2015.7

  The present work addresses a development of metal free one pot direct method for sulfenylation of active methylene compounds and indole. The reaction might proceed through sulfenyl bromide as an intermediate, which initiates the C-S bond formation. The reaction was performed using tetrabutylammonium tribromide (TBATB) as a brominating agent, CH2Cl2 as a solvent at room temperature. (C) 2015 Elsevier Ltd. All rights reserved.
