Preparation and Characterization of Methyl Substituted 2,2′-Dipyridyl Diselenides, 2,2′-Dipyridyl Ditellurides, and Their Derivatives

Abstract

Abstract A number of methyl substituted 2,2′-dipyridyl diselenides and -ditellurides have been prepared. Effect of the solvent and the substituents on the rate of these reactions have also been studied. The preparation of 2-methylseleno/telluro picolines by reductive cleavage of the diselenides and ditellurides and by one pot reaction using n-BuLi at −78°C in THF is reported.
