Potassium 2-arylethyneselenolates enter into cyclization with phenyl isoselenocyanate to form the products from 1,3-anionic cycloaddition, i.e., 2-phenylimino-4-aryl-1,3-diselenoles.Donating substituents accelerate and accepting substituents retard this reaction.If the potassium is substituted by lithium, the yield of the cyclization products is substantially reduced. 2-Phenylimino-4-aryl-1,3-diselenoles are converted by treatment with methyl iodide into 2-(N-methylphenylamino)-4-aryl-1,3-diselenolium iodides, which form 4-aryl-1,3-diselenole-2-selenones under the influence of hydrogen selenide.
