Hey tried to workout a alternative (cheaper) route to P2NP with the help of AI. But bc you can't trust it, even if you ask several different ones, I would like to ask the real chemists to find the mistakes or difficulties in the following synth
1. Base preparation: Dissolve KOH in IPA (solvent).
2. Activation: Add nitromethane to the KOH solution under strong cooling.
3. Ketone addition: Slowly add acetophenone while keeping temperature low
4. Reaction progression:
After exotherm slows, warm to room temperature (~1 h).
Maintain ~50 °C for 2 h to complete reaction.
5. Isolation: Slowly acidify with dilute acid (10 % HCl) to pH ~7 to precipitate the product.
6. Filter and Clean
Theoretical Yield should be 1eq P2NP
- Acetophenon: 1 eq
- Nitromethan: 4 eq
- KOH: 1 eq
- Isopropanol (IPA): 150 mL
