Research output: Contribution to journalArticle


The synthesis of γ-lactones from the addition products of ketene thioacetal anions and carbonyl compounds has been achieved. A unique phenylselenenyl chloride triggered formation of dithienium ion from ketene thioacetal has been shown to directly afford a doubly protected butenolide system.
