This review intends to cover the synthesis of both mono-and di-chalcogenides of 2-, 3-and 4-
pyridyl and 2-pyrimidyl groups, their spectroscopic and structural studies. The 77Se and …

Selenium is a member of the group 16 elements (O, S, Se, Te and radioactive Po),
collectively known as chalcogens. It was discovered in 1817 by JJ Berzelius in the reddish …

Pyridyl and pyrimidyl based organoselenium compounds have been synthesized and
characterized by analytical and spectroscopic techniques. Molecular structures of 2, 2 …

A series of 2-(3, 5-dimethylpyrazol-1-yl) ethylseleno derivatives has been synthesized. The
glutathione peroxidase like catalytic activity of these compounds has been studied in a …

This article describes the prime role of selenium (Se) and its compounds in mammalian
biochemical systems, performing diverse functions like maintenance of health through …

A mild approach for the synthesis of halogenated 4-pyrazolylspirocyclic-β-lactams via
halogen (I 2, Br 2, ICl) mediated intrasulfenyl cyclisation of cis-3-(prop-2′-ynyloxy)-4 …

An efficient one-pot synthesis of β-lactams by the reaction of imines with acetic acid
derivatives in the presence of DMF and benzoyl chloride adduct, a cheap reagent, has been …

Organoselenium compounds have long been fascinated researchers owing to their wide
range of applications, such as in anticancer, in catalysis, and as molecular precursors for …

Since its discovery 200 years ago, in 1817, by Jöns Jacob Berzelius (1779–1848), the
element selenium has had a rather chequered relationship with biology and medicine, an …

Thiocarbonyldiimidazole has been found to be an efficient acid activator for the synthesis of
β-lactams by ketene-imine cycloaddition at room temperature. The experimental procedure …
