Vibrational spectra and trace determination of p-difluorobenzene and ethylbenzene.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 107 , 1-7, (2013) In this work, the structures and normal vibrations of p-difluorobenzene and ethylbenzene in the first excited state have been studied using resonant two-photon ionization spectrum and ab initio quantum chemical calculations. A vibronic spectrum of p-difluorob... |

Ionized o-, m-, and p-difluorobenzene dissociate through ring-opened intermediates: a TPEPICO investigation.
J. Am. Soc. Mass Spectrom. 20(1) , 20-4, (2009) Threshold photoelectron photoion coincidence (TPEPICO) experiments have shown that o-, m-, and p-difluorobenzene ions dissociate via a common, ring-opened intermediate and not via ionized p-difluorobenzene. Rice-Ramsperger-Kassel-Marcus (RRKM) modeling of the... |

Regioselectivity of cytochrome P-450 catalyzed hydroxylation of fluorobenzenes predicted by calculated frontier orbital substrate characteristics.
Biochemistry 32(18) , 4801-12, (1993) In the present study, a hypothesis is presented for the prediction of the regioselectivity of cytochrome P-450 catalyzed hydroxylation of fluorobenzenes. The regioselectivity of the in vivo hydroxylation of fluorobenzene, 1,2-difluorobenzene, 1,3-difluorobenz... |

The effects of volatile aromatic anesthetics on voltage-gated Na+ channels expressed in Xenopus oocytes.
Anesth. Analg. 107(5) , 1579-86, (2008) Many inhaled anesthetics inhibit voltage-gated sodium channels at clinically relevant concentrations, and suppression of neurotransmitter release by these anesthetics results, at least partly, from decreased presynaptic sodium channel activity. Volatile aroma... |

Hexafluorobenzene acts in the spinal cord, whereas o-difluorobenzene acts in both brain and spinal cord, to produce immobility.
Anesth. Analg. 104(4) , 822-8, (2007) Previous work demonstrated that isoflurane and halothane act on the spinal cord rather than on the brain to produce immobility in the face of noxious stimulation. These anesthetics share many effects on specific receptors, and thus do not test the broad appli... |

Novel synthesis of desymmetrized resorcinol derivatives: aryl fluoride displacement on deactivated substrates.
J. Org. Chem. 71(5) , 2170-2, (2006) A short, high-yielding synthesis of differentially substituted resorcinol derivatives has been developed that utilizes 1,3-difluorobenzene as the starting material and employs sequential nucleophilic aromatic substitution (S(N)Ar) reactions to generate desymm... |

The effects of aromatic anesthetics on dorsal horn neuronal responses to noxious stimulation.
Anesth. Analg. 106(6) , 1759-64, (2008) Gamma-aminobutyric acid type A receptor potentiation and/or N-methyl-d-aspartate (NMDA) receptor inhibition might explain the anesthetic properties of fluorinated aromatic compounds. We hypothesized that depression of dorsal horn neuronal responses to noxious... |
