Recent Progress in Imidoselenium Chemistry

Recent progress in imidoselenium chemistry is reviewed. Selenium diimides are thermally unstable and decompose forming a number of cyclic selenium imide derivatives Se₃(NR)₂, Se₃(NR)₃, Se₆(NR)₂, Se₉(NR)₆, OSe(μ-NR)₂SeO, RNSe(μ-NR)₂SeO, and RNSe(μ-NR)₂SO₂ (R = ^t Bu or adamantyl). All species have been structurally characterized. The experimental and theoretical evidence for the possibility of [2 + 2] cyclodimerization of selenium diimides is discussed.

Keywords:

• NMR spectroscopy
• selenium imides
