Abstract
A number of unsymmetrical alkyl/allyl-2-fluoro-3-pyridyl tellurides and bis(2-fluoro-3-pyridyltelluro)methane have been prepared by the reductive cleavage of bis(2-fluoro-3-pyridyl)ditelluride with sodium borohydride followed by quenching of the intermediate 2-fluoro-3-pyridyl tellurolate anion with appropriate alkylating agents. All the newly synthesized compounds have been characterized with the help of elemental analysis and by employing various spectroscopic techniques: Fourier transform infrared (FT-IR), multinuclear (1H, 13C, 19F, 125Te) nuclear magnetic resonance (NMR) spectroscopy, and mass spectrometry (in representative cases). The crystal structure of bis(2-fluoro-3-pyridyltelluro)methane has been determined by single crystal X-ray diffraction.
