✦ Synopsis

The reaction of elemental Se with 1,3-dimethyIimidazolium iodide in methanolic K2C03 yields 1,3-dimethyl-2(3H)-imidazoleselone for which three addition products, two with bromine and one with iodomethane, have been synthesized and for which Xray crystallographic analysis shows the structure to consist of a selenium-substituted planar heterocyclic ring with bond distances and angles significantly different from those noted for the previously reported sulfur analog [1,3-dimethy1-2(3H)-imidazolethione, dmit]. Crystal data: C5H8Nse, space group C mcm,
