Synthesis and Characterization of Symmetrical and Unsymmetrical Analogues of 1,2-bis[bis(4-chlorophenyl) Methyl] Diselane

Abstract

The 'living' species selenide anion Se 2 2-, generated in situ by the reduction of 1,2-bis(bis(4-chlorophenyl)methyl)diselane with sodium borohydride, was treated with various organic halides to afford synthetically important organoselenium compounds including α,ω-diselenoethers and selenides bearing ester functionality, under mild and neutral conditions. These compounds have been characterized analytically with the help of various spectroscopic techniques viz., IR, multinuclear NMR (1 H, 13 C, 77 Se) and mass spectrometry.
