Phosphazene base P2-t-Bu solution
Phosphazene base P2-t-Bu solution (CAS: 111324-03-9; Formula: C14H39N7P2; MW: 367.45 g/mol) is an exceptionally strong, non-ionic nitrogen base. Supplied as approximately a 2.0 M solution in THF, this compound serves as a potent reagent in organic synthesis. Its high basicity makes it suitable for demanding deprotonation reactions and other applications requiring a powerful, yet non-nucleophilic, base.
- IUPAC
- 1-tert-Butyl-2,2,4,4,4-pentakis(dimethylamino)-2λ5,4λ5-catenadi(phosphazene)

Organic Synthesis Reagent
Utilised as a strong, non-nucleophilic base in various organic transformations. Its high basicity facilitates difficult deprotonations and other reactions where conventional bases may be insufficient.
Deprotonation Reactions
Effective for removing protons from weakly acidic compounds due to its extreme basicity. This makes it valuable in forming carbanions or other reactive intermediates.
Catalysis
Can act as a catalyst or co-catalyst in specific chemical reactions, leveraging its unique structural and electronic properties.
