  to promote ortho‐C−H metalation. Based upon this reactivity, we employed an activated norbornene that traps the ortho‐palladation intermediate and is then relayed to the meta position, leading to meta‐selective C−H arylation of fluoroarenes. Deuterium experiment suggests that this meta‐arylation is initiated by ortho C−H activation and the catalytic cycle is terminated by C‐2 protonation. A dual‐ligand

  已知氟可促进邻位‐C−H 金属化。基于这种反应性，我们采用了一种活化的降冰片烯来捕获邻位钯化中间体，然后转移到间位，从而导致氟芳烃的间位选择性C−H 芳基化。氘实验表明，这种元芳基化是由邻位C-H 激活引发的，催化循环由 C-2 质子化终止。双配体系统对于观察到的高反应性和位点选择性至关重要。将这种方法应用于简单的苯或其他芳烃也可以提供具有良好收率和位点选择性的芳基化产物。

  Regioselective preparations of a number of fluorinated phenyllithiums have recently been reported, which in some cases also contain one or more bromine substituents. These have now been applied to the synthesis of the corresponding halogenated 2-arylpropenes (α-methyl- styrenes), benzhydrols, trifluoromethylbenzhydrols, benzophenones and aryltrimethylsilanes.

• Determination of the gas-phase acidities of halogen-substituted aromatic compounds using the silane-cleavage method
  作者：Paul G. Wenthold、Robert R. Squires

  DOI：10.1002/jms.1190300105

  日期：1995.1

  The gas-phase acidities of halogen-substituted aromatic compounds have been determined in a flowing afterglowtriple quadrupole apparatus with use of the silane cleavage method developed by DePuy and co-workers [C. H. DePuy, S. Gronert, S. E. Barlow, V. M. Bierbaum and R. Damrauer, J. Am. Chem. Soc., 111, 1968 (1989)]. In this method the relative yields of siloxide ion products produced in reactions of OH− with trimethylsilyl- or phenyldimethylsilyl-substituted aromatic compounds are correlated with the difference in gas-phase acidity of the accompanying neutral products. Acidities are reported for different ring-positions in fluoro-, chloro- and bromobenzene, chloro- and bromonaphthalene and benzyl chloride. Excellent precision is achieved in most cases, with assigned uncertainties less than 2–3 kcal/mol. Good agreement is obtained between the acidities determined with use of two different types of silane precursor. Halogen-substitution increases the gas-phase acidities of benzene and naphthalene by similar amounts (13–14 kcal/mol). The effects on different ring-positions in benzene and naphthalene are shown to be primarily inductive in nature, falling-off by a consistent 2.5–3.5 kcal/mol per bond separating the acidic site from the halogen-bearing carbon in the chlorine and bromine-substituted systems. Larger effects are evident in the positional acidities of fluorobenzene. The meta and para position acidities of halobenzenes are shown to be linearly correlated with the acidities of the corresponding meta and para halophenols, haloanilines and halotoluenes.

  卤素取代的芳香化合物的气相酸性通过使用DePuy及其合作者开发的硅烷裂解法在流动后辉三重四极杆仪器中进行了测定[C. H. DePuy, S. Gronert, S. E. Barlow, V. M. Bierbaum和R. Damrauer, J. Am. Chem. Soc., 111, 1968 (1989)]。在该方法中，与OH−与三甲基硅基或苯基二甲基硅基取代芳香化合物反应所生成的硅氧负离子产物的相对产率与伴随的中性产物的气相酸性差异相关联。不同环位的氟、氯和溴苯、氯和溴萘以及苄氯的酸性结果已被报告。在大多数情况下实现了优异的精确度，赋值不确定性低于2-3 kcal/mol。使用两种不同类型的硅烷前体测定的酸性结果之间获得良好的一致性。卤素取代使苯和萘的气相酸性均增加了相似的值（13-14 kcal/mol）。氯和溴取代体系中，苯和萘中不同环位的影响主要是感应效应，酸性位点与含卤碳原子之间每隔一个键的酸性降低幅度一致为2.5-3.5 kcal/mol。在氟苯的位置酸性中，明显表现出更大的影响。卤苯的对位和间位酸性与相应的间位和对位卤酚、卤代苯胺和卤代甲苯的酸性呈线性相关。
