How do the yields of quinones and diquinones vary with different ceric ammonium nitrate (CAN) addition methods?

Label:chem

Topic
A study evaluates the yields of quinones and diquinones produced using traditional and inverse addition methods of CAN.
Answer
The yields of quinones 4a and 4b were 69% and 78%, respectively, using the traditional addition method. In contrast, the yields of diquinones 5a and 5b were significantly higher at 84% and 88%, respectively, using the inverse addition method. This indicates that the inverse addition method is more efficient for diquinone formation, while the traditional method is more suitable for quinone formation.
