• Chemical shifts of phenolic monomers in solution and implications for addition and self-condensation
  作者：Robert A. Haupt、Scott Renneckar

  DOI：10.1002/mrc.3914

  日期：2013.2

  Alkali metal counter-cations alter the electron density of phenolates in solution by electrostatic interactions. This change in electron density affects their reactivity toward formaldehyde, hydroxymethylphenols, and isocyanates during polymerization. The electronic perturbation of phenolic model compounds in the presence of alkali metal hydroxides was investigated with (13)C and (1)H nuclear magnetic

  碱金属抗衡阳离子通过静电相互作用改变溶液中酚盐的电子密度。电子密度的这种变化会影响它们在聚合过程中对甲醛，羟甲基苯酚和异氰酸酯的反应性。相对于非离子对照物，在极性溶剂中用（13）C和（1）H核磁共振研究了碱金属氢氧化物存在下酚类化合物的电子扰动，从而改变了模型化合物的化学位移，从而表明以化学位移为代表的电子密度变化。这些变化归因于抗衡阳离子与酚醛阴离子的库仑静电相互作用，该相互作用与水合离子半径和溶剂介电常数有关。基于酚模型的（13）C核磁共振的电子密度等级，将甲醛添加的预计相对反应速率与文献值进行了比较。由化学位移对2-和4-羟甲基苯酚的缩合反应的预测与已发表的结果一致。结果允许预测酚类化合物用于形成热固性聚合物材料的反应。

  A process for producing a cyclic and/or linear phosphonitrilic acid ester from a cyclic and/or linear phosphonitrile dichloride is provided, wherein the reaction time is shorter and the content of monochloro phosphazenes is very small. When phosphonitrile dichloride is reacted with a metal arylolate and/or a metal alcoholate in the presence of a reaction solvent, a metal arylolate and/or a metal alcoholate composed of at least two different metals having different ionization energies is used and also a specific compound is used as a catalyst.

• Benzylic C–H activation and C–O bond formation via aryl to benzylic 1,4-palladium migrations
  作者：Tanay Kesharwani、Richard C. Larock

  DOI：10.1016/j.tet.2008.01.144

  日期：2008.6

  A procedure for benzylic C-H activation has been developed using a palladium 1,4-aryl to benzylic migration as a key step. Carboxylates and phenoxides readily trap the resulting benzylic palladium intermediates obtained from palladium 'through space' migration. Aryl bromides and iodides have been successfully employed in this reaction, furnishing moderate to good yields. The mechanism of this reaction has been studied by deuterium-labeling experiments, which suggest that the migration of palladium from an aryl to a benzylic position occurs reversibly. The reaction conditions developed for the migration process also oxidize the neighboring benzylic alcohols to the corresponding aldehydes and ketones. (C) 2008 Elsevier Ltd. All rights reserved.
