Abstract

A silver-catalyzed method provides a practical, highly efficient, and straightforward route to substituted quinolin-2-ones or 3,4-dihydroquinolin-2-ones in one step through an intermolecular radical addition/cyclization in aqueous solution. A mechanism for the formation of quinolin-2-ones is proposed.
