Potassium 2-aryl- and 2-alkylethyneselenolates, obtained by the decomposition of 4-substituted 1,2,3-selenadiazoles, enter into a cyclization reaction with phenyl isothiocyanate to form isomeric N-(5-R-1,3-thiaselenol-2-ylidene)phenylamines.Measurement of the relative rate constants for cyclization of 2-(p-R-aryl)ethyneselenolates at the thione bond shows that the reaction is accelerated by donating substituents and retarded by withdrawing substituents.

Reaction of 5-substituted 2-thioxo-1,3-thiaselenoles with ethyl diazoacetate, phenyl azide and ethyl azidoformate afforded 2-substituted ω-carbethoxy-1,4-thiaselenafulvenes (II), 5-substituted 2-phenylimino-1,3-thiaselenoles (IV) and 5-substituted 2-carbethoxyimino-1,3-thiaselenoles (V), respectively.The structure of these compounds were confirmed by spectroscopic methods and chemical analysis.
