Potassium tert-butoxide Structure

density 0.910 g/mL at 20 °C

Potassium Tert-butoxide Application

1. Used in pesticides, medicines, printing and dyeing, catalysts, etc.
2. As a strong base, it is widely used in the condensation, rearrangement and ring opening reactions in organic synthesis such as chemical, pharmaceutical and pesticide.
3. It is a moderately strong base commonly used in organic synthesis.
4. The reason why t-BuOK is widely used is that it is inexpensive and readily available, and its basicity changes depending on the selected reaction solvent.
5. For Stobbe condensation, t-BuOK is a better base than EtONa, with higher reaction yield, shorter reaction time, and no side reactions of ketone or aldehyde reduction.
