CAS 40949-94-8: Potassium bis(trimethylsilyl)amide

Description:Potassium bis(trimethylsilyl)amide, with the CAS number 40949-94-8, is an organopotassium compound that serves as a strong base and nucleophile in organic synthesis. It is characterized by the presence of a potassium cation (K+) and a bis(trimethylsilyl)amide anion, which consists of two trimethylsilyl groups attached to a nitrogen atom. This compound is typically a white to light yellow solid that is highly reactive, particularly with moisture, and should be handled under inert atmospheres to prevent hydrolysis. Its strong basicity makes it useful in deprotonation reactions and as a reagent for the synthesis of various organic compounds, including amines and other nitrogen-containing species. Additionally, it is employed in the preparation of silylated compounds and can facilitate the formation of carbon-nitrogen bonds. Due to its reactivity, proper safety precautions should be taken when handling this substance, including the use of gloves and eye protection, as it can cause irritation and is potentially hazardous.
