An efficient method for the synthesis of symmetrical diselenides is described. Reductive selenation of aromatic and heterocyclic aromatic aldehydes (ArCHO) with Se/CO/H2O in DMF afforded diselenides (ArCH2SeSeCH2Ar) in yields up to 94% underatmosphericpressure without use of a base.

An improved method for the synthesis of symmetrical diselenides is described. Reductive selenation of aromatic aldehydes with Se/CO/H2O/Et3N system in THF gave the corresponding aromaticdiselenides in good yields.
Design, synthesis and characterization of picoline based organoselenium compounds, 1,2-bis(pyridine-2/3/4-yl)methyl diselanes: X-ray crystal structure of 1,2-bis(pyridine-3-yl)methyldiselane
An efficient synthetic protocol affording symmetrical 1,2-bis(pyridine-21314-yl)methyldiselanes from pyridine-21314-carbaldehyde in high yields at room temperature, without using highly toxic hydrogen selenide, has been developed. The synthesis involves the reductive selenation of pyridine-21314carbaldehyde with sodium hydrogen selenide, NaHSe in the presence of piperidine hydrochloride followed by NaBH4 reduction under mild conditions. Primary screening of the anti-proliferative activity of the newly synthesized compounds against several mammalian cell lines and pathogenic strains has been carried out. The crystal structure of 1,2-bis(pyridine-3-yl)methyldiselane has been established by X-ray diffraction analysis. (C) 2015 Elsevier BY. All rights reserved.
