Radical rebound process
WebMar 23, 2024 · Attack of Boc 2 O on radical intermediate D prior to radical rebound cannot be fully excluded on the basis of the available experimental data. However, in view of the very low computed barrier for the radical rebound step (<2 kcal mol −1), this pathway seems unlikely. Additional catalytic experiments based on the mechanistic insights gathered WebJun 22, 2024 · West said P450 finds carbon-hydrogen bonds and removes the hydrogen, leaving a carbon-centered radical that includes an unpaired electron. “That electron really wants to find a partner, so the P450 will immediately give back an oxygen atom (the ‘rebound’), oxidizing the molecule,” he said.
