Abstract

Abstract Carbonyl-stabilized sulfonium ylides readily react with elemental sulfur and selenium to afford 1, 3-oxathiole and 1, 3-oxaselenole derivatives, respectively, in good yields, thus providing a simple method for constructing these ring systems which uses easily accessible compounds as starting materials.
