  Novel ipso-Substitution of p-Sulfinylphenols through the Pummerer-Type Reaction:  A Selective and Efficient Synthesis of p-Quinones and Protected p-Dihydroquinones

  摘要：

  The treatment of p-sulfinylphenols 3a-q with trifluoroacetic anhydride caused a Pummerer-type reaction on aromatic rings and concomitant desulfurization to give mixtures of the corresponding p-dihydroquinones 9 and p-quinones 10, which were subsequently oxidized under mild conditions to provide high yields of p-quinones 10. On the other hand, the treatment of p-(phenylsulfinyl)-phenyl ethers 6 with trifluoroacetic anhydride in the presence of styrene caused the direct ipso-substitution of the sulfinyl groups into trifluoroacetoxy groups, giving the protected dihydroquinones 14 in high yields. Both types of reactions were generally completed below room temperature within 1 h and compatible with various functional groups such as the allyl, carbonyl, ester, amide, and silyloxy groups. The preparation of the p-sulfinylphenols 3 and the silyl ethers 6 is also described through p-specific thiocyanation of phenols followed by the Grignard reaction and oxidation.

  An environmentally benign method for the synthesis of aryl sulfides in water under mild conditions has been realized, in which arenes are coupled with equal stoichiometry of allyl sulfides. This arylthiolation is enabled by the presence of the Lipshutz surfactant, TPGS-750-M, using water as the recyclable reaction medium.

  system based on deep eutectic solvents and palladium nanoparticles where C−S bonds are formed from aryl boronic acids and sodium metabisulfite, is introduced. The functionalization step is compatible with a broad spectrum of reagents such as nucleophiles, electrophiles or radical scavengers. This versatile approach allows the formation of different types of products in an environmentally friendly medium

  介绍了一种基于深共熔溶剂和钯纳米粒子的独特的曲线锯催化系统，其中钯键由芳基硼酸和焦亚硫酸钠形成。官能化步骤与诸如亲核试剂，亲电试剂或自由基清除剂的多种试剂兼容。这种通用的方法允许通过选择反应的组成部分（在拼图中彼此接合）在环境友好的介质中形成不同类型的产品。这种简单的步骤避免了使用有毒的挥发性有机溶剂，从而在温和条件下的一锅反应中形成了复杂的分子。尽管事实上仅使用了1 mol％的金属负载量，但催化系统的可回收性还是可能的。进行了动力学实验，并确定了所有试剂，催化剂和配体的反应顺序。将获得的结果与已知形状不同的钯纳米晶体进行比较，以便对催化剂的性能有所了解。
