UNSATURATED THIOLATES AND THEIR ANALOGS IN CYCLOADDITION REACTIONS. XIII. REACTIONS OF POTASSIUM 2-ARYL- AND 2-ALKYLETHYNESELENOLATES WITH HETEROCUMULENES

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.
