Preparation of 1,3-Selenazol-4-one Derivatives from Primary Selenoamides and Haloacyl Halides

Abstract

1,3-Selenazol-4-one derivatives were synthesized by the reaction of primary selenoamides with haloacyl halides in the presence of pyridine.

Key words

primary selenoamide - haloacyl halide - pyridine - 1,3-selenazol-4-one - heterocycles
