The reaction of [(Me3Si)(2)N](2)S with an equimolar amount of SeCl4 in CS2
or CH2Cl2 at -70 degreesC provides a route to 1,5-Se2S2N4 in a good yield.
When the reaction is carried out in dioxane at +50 degreesC five membered h
eterocycle (SSe2N2Cl)(2) is formed. The product is identified and character
ized using X-Ray diffraction, Raman spectroscopy, mass spectroscopy and NMR
spectroscopy. Se-77 MAS NMR study of the 1,5-Se2S2N4 is reported.
