  Interbenzylic19F,19F spin-spin coupling constants in bis(fluoromethyl) arenes

  摘要：

  AbstractFive‐ to eleven‐bond F,F spin coupling is observed in bis(fluoromethyl)arenes. According to INDO MO calculations, these couplings are transmitted mainly via the aromatic π‐system. The low preference of 1,4‐(CH2F)2‐benzene for the conformation in which the CF bonds are perpendicular to the aromatic ring is shown by the strong increase of7J(FF) upon double ortho‐substitution.

• A Class of Phase-Transfer Catalyst with Interionic Strain: Insight into the Bonding of Disubstituted N- vs Carbene-Stabilized N^I-Centered Cations
  作者：Roya Mirabdolbaghi、Travis Dudding、Theocharis Stamatatos

  DOI：10.1021/ol501068f

  日期：2014.6.6

  The straightforward synthesis of a class of nitrogen-based phase transfer catalysts (PTCs) having markedly dissociated anions due to interionic donor-donor "ion pair strain" and use for catalyzing benzylation and benzylic fluorination is reported. Provided also is insight into the bonding of disubstituted N- vs so-called divalent carbene-stablized N-I-centered cations and the unprecedented finding of a cyclopropenium based C-H... pi(aryl) interaction.
