• Proton Mobility in 2-Substituted 1,3-Dichlorobenzenes: “ortho” or “meta” Metalation?
  作者：Manfred Schlosser、Christophe Heiss、Elena Marzi、Rosario Scopelliti

  日期：2006.10

  Nine 1,3-dichlorobenzene congeners were selected as model compds. to assess the relative rates of proton abstraction from 4- and 5-positions ("ortho" vs. "meta" metalation). Using lithium 2,2,6,6-tetramethylpiperidide as the basic reagent, the chlorine-adjacent 4-position underwent metalation exclusively. In contrast, attack at the chlorine-remote 5-position became significant even in the case of moderately

  选择九个 1,3-二氯苯同系物作为模型化合物。评估从 4 位和 5 位（“邻位”与“元”金属化）提取质子的相对速率。使用 2,2,6,6-四甲基哌啶锂作为碱性试剂，4 位氯附近专门进行金属化。相比之下，当使用仲丁基锂时，即使在中等大小的 2-取代基（如二甲氨基或乙基）的情况下，对氯远程 5-位的攻击也变得显着。“邻位/对位”(4-/5-) 比率范围为 80:20 至 65:35。与碳取代基相反，硅更显着的“元取向”效应可归因于芳族的 pi 极化的不同。戒指。[在 SciFinder (R) 上]
