  摘要：

  9,10-Dihydrophenanthrenes and phenanthrenes, mimics of natural compounds with strong antialgal activity, have been synthesized through cross-coupling of 1-(2-iodo-5-methoxy)-phenylethanol with variously substituted iodobenzenes. The synthetic compounds, bearing a hydroxyl or a methoxyl group at C-2 and a methyl in the C ring, were tested against the green alga Selenastrum capricornutum. All compounds, except 2-methoxy-7-methylphenanthrene, caused inhibition of algal growth by more than 70% at 10(-4) M, and many of them retained this strong activity at 10(-5) M.

  metal‐free and chemoselective oxidative intramolecular coupling of arene and alkene C−H bonds is reported. The active hypervalent iodine (HVI) reagent, generated catalytically in situ from iodotoluene and meta‐chloroperoxybenzoic acid (m‐CPBA), reacts with o‐vinylbiphenyls to generate polyaromatic hydrocarbons in up to 95 % yield. Experimental evidence suggests the reactions proceed though vinyliodonium

  据报道，芳烃和烯烃CH键具有催化，无金属和化学选择性的氧化分子内偶联作用。由碘代甲苯和间氯过氧苯甲酸（m- CPBA）原位催化生成的活性高价碘（HVI）试剂与邻乙烯基联苯反应生成多芳烃，产率高达95％。实验证据表明，反应是通过乙烯基碘鎓和（可能的）亚乙烯基phen中间体进行的。
• Hypervalent iodine-mediated oxidative alkene arylation: a thorough analysis

  A hypervalent iodine (HVI)-mediated, oxidative alkene arylation reaction has been developed. Both Koser’s reagent (PhI(OH)OTs) and (diacetoxyiodo)toluene (TolI(OAc)₂) were equally viable as oxidants, which reacted with ortho-vinylbiphenyl derivatives to produce tri-, tetra-, and pentacyclic polycyclic aromatic hydrocarbons in yields up to 97%. Comparison of this stoichiometric reaction with a previously reported catalytic process showed that these protocols were largely complementary, and that they likely operate via the same general mechanistic sequence involving vinyliodonium salts decomposing into vinylene phenonium ions. Various mechanistic control experiments were conducted, which ruled out epoxides as intermediates, and which showed that E- and Z-alkene geometry in 10-substituted ortho-vinylbiphenyls had no impact on the ensuing isomeric product distributions. These experiments strongly supported the formation of E-vinyliodonium ions as initial reaction intermediates, and while the occurrence of 1,2-phenyl shift products was a common phenomenon, we concluded that alkyl substitution on the ortho-vinylbiphenyl was a requirement for this alternate pathway to occur.

  我们开发了一种以高价碘 (HVI) 为介质的氧化烯芳基化反应。Koser 试剂（PhI(OH)OTs）和（二乙酰氧基碘）甲苯（TolI(OAc)2）同样可用作氧化剂，它们与正乙烯基联苯衍生物反应生成三环、四环和五环多环芳烃，收率高达 97%。将这一化学反应与之前报道的催化过程进行比较后发现，这两种方法在很大程度上是互补的，它们很可能通过相同的机理顺序进行操作，即乙烯基碘鎓盐分解成乙烯基鎓离子。我们进行了各种机理控制实验，排除了环氧化物作为中间体的可能性，实验结果表明，10-取代正乙烯基联苯中的 E-和 Z-烯几何形状对随后的异构产物分布没有影响。这些实验有力地支持了 E-乙烯基碘离子作为初始反应中间体的形成，虽然 1,2-苯基转变产物的出现是一个普遍现象，但我们得出结论，正乙烯基联苯上的烷基取代是发生这种替代途径的必要条件。
