Organotellurium compounds are proving important precursors for the generation of semiconducting materials. However, synthetic methods for their preparation involve cumbersome manipulations and require controlled experimental conditions. We wish to report a convenient method recently developed for the synthesis of this interesting class of ditellurides. The title compounds were prepared by the reaction of ditelluride anion Te2 2? with 2-bromopyridine (Scheme 1). The ditelluride anion was generated in situ by the reaction of tellurium metal with sodium borohydride in 2-ethoxyethanol. The compounds prepared were characterized by elemental analysis and through various spectroscopic techniques viz; IR, NMR (1H, 13C), mass spectral analysis, crystal structure of 2,2′-dipyridyl ditelluride is reported.
