Applications of Sodium tert-Butoxide (STB) in Tetrahydrofuran
Sterically hindered base for eliminations and base-promoted cross-couplings (Buchwald, etc.).
- Liquid formulation reduces weighing errors and improves safety/scale reproducibility.
- Standardized molarity simplifies stoichiometry control in production.
Advantages of Standardized molarity simplifies stoichiometry control in production.
Strong, sterically hindered base with high solubility in THF – reliable for many base-promoted transformations.
- Liquid formulation reduces weighing errors and dust exposure – better process control at scale.
- Effective in cross-coupling and Buchwald/Hartwig-type conditions where tert-butoxide base is preferred.
- Commercial solutions available in defined molarity for reproducible reaction stoichiometry.
