9,10-phenanthrenequinone

Fundamentals of the Reactivity of 9,10-Phenanthrenequinone and Its Derivatives: Vicinal Dicarbonyl Electronic Structure, Electron Transfer, and Photochemical Reactions

9,10-Phenanthrenequinone (PQ) is formed by converting the 9- and 10-positions of phenanthrene into two adjacent carbonyl groups and is a typical fused-ring dicarbonyl system of the ortho-quinone type. The two C=O groups are directly adjacent and connected to the peripheral aromatic π system, ...
