Carbon Suboxide in Preparative Organic Chemistry. New synthetic methods (1)

Abstract

Abstract Although it has been known for nearly 70 years, carbon suboxide was used almost exclusively for the preparation of simple malonic acid derivatives until about 1960. Since then, however, the significance of this unusual “bisketene” has steadily increased in synthetic chemistry (especially that of heterocyclic compounds). This progress report surveys the possible applications of C 3 O 2 in preparative organic chemistry, including photochemical reactions.
