2-Benzopyran-3-one

Abstract

Trapping and low temperature matrix isolation experiments show that 2-benzopyran-3-one (1) is efficiently generated by thermolysis or photolysis of the bis-lactone (2); flash vacuum thermolysis of (2) yields isocoumarin (5) and photolysis of (2) in an argon matrix gives (1) and the ketene (6).
