Abstract

Aliphatic seleno-amides are caused to react with an a -halogenated aldehyde or a -halogenated-ketone in molecular proportions and with heating, with or without a solvent, to give 2-alkylselenazoles. According to examples: (1) chloracetaldehyde is treated with selenoacetamide to give 2-methyl thiazole; (2) a -bromacetophenone with seleno-acetamide gives 4 - phenyl - 2 - methylselenazole; (3) chloracetone with selenopropionamide gives 4-methyl-2-ethylselenazole. According to the alkyl group required to occupy the 2-position the corresponding selenoamide is selected, and any a -halogenated ketone or aldehyde may be employed. Selenopropionamide is obtained by the method of Kindler, Annalen, 1923, 431, 187 using propionitrile.
