Reactions Of Substituted Quinones 【2024】

The "ortho/para" rule applies here; substituents on the diene and the quinone will orient themselves to maximize electronic stabilization in the transition state. 3. Redox Chemistry (Reduction) Quinones are easily reduced to hydroquinones.

Large groups can hinder the approach of the diene, often dictating which face of the quinone is attacked. reactions of substituted quinones

If the quinone is unsymmetrically substituted, the nucleophile typically attacks the less hindered carbon or the carbon with the lowest electron density. The "ortho/para" rule applies here; substituents on the

Electron-withdrawing groups make the quinone a stronger oxidant (easier to reduce). Electron-donating groups (like −OMenegative cap O cap M e −CH3negative cap C cap H sub 3 ) make the quinone more stable and harder to reduce. The "ortho/para" rule applies here
