CAS 865-47-4: Potassium tert-butoxide
Description:Potassium tert-butoxide (KOC(CH₃)₃) is a strong, non-nucleophilic base commonly used in organic synthesis. It appears as a white to off-white solid and is highly soluble in polar aprotic solvents such as dimethyl sulfoxide (DMSO) and tetrahydrofuran (THF). This compound is the potassium salt of tert-butyl alcohol and is known for its ability to deprotonate weak acids, making it valuable in various reactions, including elimination and substitution processes. Potassium tert-butoxide is hygroscopic, meaning it readily absorbs moisture from the air, which can affect its reactivity and storage. It is typically handled under inert atmospheres to prevent degradation and moisture absorption. Safety precautions are essential when working with this substance, as it can react vigorously with water and other protic solvents, releasing tert-butanol and potentially causing hazardous situations. Overall, potassium tert-butoxide is a versatile reagent in synthetic organic chemistry, particularly in the formation of carbon-carbon bonds and in the generation of reactive intermediates.
