Newer Aspects in Synthetic Methodology of Pyridyl Chalcogen (E═Se/Te) Compounds

Abstract

A number of synthetic protocols for the synthesis of symmetrical dipyridyl chalcogenides/dichalcogenides have successfully been developed by employing cheap, economically viable and eco-friendly reagents. The reductive cleavage of Se–Se and Te–Te bond in these versatile compounds conveniently have been achieved and a number of hitherto unknown chelating seleno/telluro ethers with varying back bones have been prepared employing appropriate alkylating agents.
