Synthesis and decarboxylative Wittig reaction of difluoromethylene phosphobetaine.
Chem. Commun. (Camb.) 49(68) , 7513-5, (2013) A key intermediate, difluoromethylene phosphobetaine, in the Wittig reaction of ClCF2CO2Na-Ph3P with aldehydes was synthesized and characterized, which confirmed the reaction mechanism. The decarboxylation of this stable intermediate was a convenient approach... |

Chlorodifluoroacetic acid fate and toxicity to the macrophytes Lemna gibba, Myriophyllum spicatum, and Myriophyllum sibiricum in aquatic microcosms.
Environ. Toxicol. Chem. 20(12) , 2758-67, (2001) Chlorodifluoroacetic acid (CDFA) is a novel haloacetic acid (HAA) and has been recently documented in aquatic systems. It is a suspected degradation product of the refrigerants 1,1,2-trichloro-1,1-difluoroethane (CFC-113) and 1-chloro-1,1-difluoroethane (HCFC... |

Metabolism of the hydrochlorofluorocarbon 1,2-dichloro-1,1-difluoroethane.
Chem. Res. Toxicol. 4(2) , 180-6, (1991) 1,2-Dichloro-1,1-difluoroethane (HCFC-132b) is a potential substitute for some ozone-depleting chlorofluorocarbons and a model for other 1,1,1,2-tetrahaloethanes under consideration as chlorofluorocarbon substitutes. Male Fischer 344 rats were given 10 mmol/k... |

Changes in tropospheric composition and air quality due to stratospheric ozone depletion.
Photochem. Photobiol. Sci. 2(1) , 62-7, (2003) Increased UV-B through stratospheric ozone depletion leads to an increased chemical activity in the lower atmosphere (the troposphere). The effect of stratospheric ozone depletion on tropospheric ozone is small (though significant) compared to the ozone gener... |

Low energy (0-10 eV) electron driven reactions in the halogenated organic acids CCl3COOH, CClF2COOH, and CF3CHNH2COOH (trifluoroalanine).
J. Chem. Phys. 135(12) , 124307, (2011) Negative ion formation following resonant electron attachment to the three title molecules is studied by means of a beam experiment with mass spectrometric detection of the anions. All three molecules exhibit a pronounced resonance in the energy range around ... |

35Cl NOR and 19F NMR relaxation studies of CClF2 group dynamics in N(CH3)4H(ClF2CCOO)2.
Solid State Nucl. Magn. Reson. 6(2) , 141-6, (1996) The reorientation of CClF2 groups in N(CH3)4H(ClF2CCOO)2 has been studied using pulsed NQR and NMR techniques. The temperature dependence of both chlorine (35Cl) NQR and fluorine (19F) NMR spin-lattice relaxation has been measured T1Q of chlorine is attribute... |
