✦ Synopsis

Photocleavage Coupling Reactions Between Cyclohexa-2,4-dienone Sulfone Derivatives and Amines by Visible Light Irradiation. -The readily available title sulfone (IV) undergoes facile ring cleavage under visible light irradiation to produce a ketene intermediate, that can be efficiently captured by amines to give amides [cf.(X)] even in the presence of competing nucleophiles such as water or ethanol [→(VIII)]. -(KIM, YOUNG MEE;
