Abstract

The reaction of elemental Se with 1,3-dimethylimidazolium iodide in methanolic K2CO3 yields 1,3-dimethyl-2(3H)-imidazoleselone (I) for which three addn. products, two with bromine and one with iodomethane, have been synthesized and for which X-ray crystallog. anal. 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-dimethyl-2(3H)-imidazolethione, dmit].
