  CAN- and DDQ-Promoted Oxidation of Alkenyl Sulfides

  摘要：

  Vinyl sulfides 1 react with CAN in acetonitrile at room temperature to give radical cations 2A in equilibrium with the thiiranyl radical cations 2B. The reaction products arise from nucleophilic attack of the nitrate counterion at either the sulfur atom of 2A or the trivalent carbon of 2B. The last reaction can proceed through 1,2-shift or displacement of the sulfide moiety. When alpha-methylenic protons are present in 2B, deprotonation occurs, leading to allyl radicals and, ultimately, to isomeric allyl alcohols. Reactions of 1 with DDQ in acetonitrile afford charge-transfer complexes and then zwitterionic electron-transfer (ET) complexes which can evolve rapidly through intramolecular proton transfer when trans methylenic protons are present. The resulting sulfur-oxygen sigma-complexes are responsible for the reaction products mainly through either gamma-elimination of DDQH(2) or nucleophilic attack at the delta-vinylic carbon followed by displacement of DDQH(-).

  巯基自由基除炔烃外。硫烷基自由基加成和氢原子抽象的相对反应速率

  摘要：

  2-（甲苯硫基）-1和2-（苯硫基）-苯乙炔10在AIBN存在下分别于84和154°C与苯硫醇和甲苯硫醇反应，制得衍生自乙烯基2的产物，该产物进行氢抽象反应和5 -邻位和5- exo环化到两个相邻的苯环上，与β片段竞争。已经获得明确的证据，将烷硫烷基加到炔三键是不可逆的过程，而芳烃硫烷基则以可逆的方式加成。为了确定向炔烃三键（k 1）加成的硫烷基的相对速率常数和由所得乙烯基自由基引起的氢夺取反应（k H），已进行了涉及几个炔烃的竞争实验，涉及到苯硫醇和苯乙硫醇基团的加成。。k 1值主要由C-（α）乙烯基自由基取代基提供的乙烯基自由基稳定性决定，而k H值似乎主要由极性因素决定。就乙烯基的不同杂化而言，讨论了α-丙基和α-长链取代基之间出乎意料的不同行为。

  The incorporation of an easily oxidized arylsulfide moiety facilitates the photocatalytic generation of alkene radical cations that undergo a variety of cycloaddition reactions with electron-rich reaction partners. The sulfide moiety can subsequently be reductively cleaved in a traceless fashion, affording products that are not otherwise directly accessible using photoredox catalysis. This approach

  易于氧化的芳基硫醚部分的引入促进了烯烃自由基阳离子的光催化生成，该自由基阳离子与富电子反应伙伴进行各种环加成反应。随后，硫化物部分可以以无痕方式还原裂解，从而提供使用光氧化还原催化无法直接获得的产物。这种方法构成了一种新颖的氧化“氧化还原辅助”策略，提供了一种实用的方法来规避光氧化还原反应面临的基本热力学限制。

  benzenethiol and benzeneethanethiol radical addition have been performed in order to determine the relative rate constants of the sulfanyl radical addition to the alkyne triple bond (k1) and the hydrogen abstraction reaction by the resulting vinyl radicals (kH). The k1 values are mainly determined by the vinyl radical stabilization provided by the C-(α) vinyl radical substituent, whereas the kH values
