The reaction of (hetero)aromatic aldehydes, cyanoselenoacetamide, and 1-(cyanoacetyl)-3,5-dimethyl-pyrazole in the presence of triethylamine gives a mixture of the cis and trans diastereomers of triethylammonium 4-aryl(hetaryl)-3,5-dicyano-6-oxo-1,4,5,6-tetrahydropyridine-2-selenolates. The selenolates obtained react with alkyl halides to form the corresponding selenides.
