Bis(trimetilsilil)amida de sodio

Descripción:

Bis(trimetilsilil)amida de sodio, comúnmente conocido como NaHM(SiMe3)2, es un compuesto organosilícico caracterizado por su fuerte basicidad y nucleofilia. Se encuentra típicamente como un sólido blanco a amarillo claro y es altamente soluble en disolventes no polares como el hexano y el tolueno, pero insoluble en disolventes polares como el agua. El compuesto presenta un catión de sodio y un anión bis(trimetilsililo)amida, lo que contribuye a su reactividad, particularmente en reacciones de desprotonación. Bis(trimetilsilil)amida de sodio se utiliza a menudo como reactivo en la síntesis orgánica, especialmente en la formación de enlaces carbono-nitrógeno y como una base fuerte en diversas transformaciones químicas. Es sensible a la humedad y al aire, requiriendo un manejo y almacenamiento cuidadosos en atmósferas inertes para prevenir la hidrólisis y degradación. Debido a su reactividad, es importante utilizar medidas de seguridad adecuadas al trabajar con este compuesto, ya que puede reaccionar vigorosamente con agua y otros disolventes proticos, liberando trimetilsilanol y subproductos potencialmente peligrosos.

Sodium bis(trimethylsilyl)amide

CAS: 1070-89-9

Sodium bis(trimethylsilyl)amide is a chemical compound with the chemical formula NaH(SiMe3). It is a solid catalyst that is used to produce polymers. It is a colorless solid and has a melting point of -41°C. Sodium bis(trimethylsilyl)amide contains one hydroxyl group in its structure and can be synthesized by reacting hydrochloric acid with cyclopentene oxide. The isolated yield of sodium bis(trimethylsilyl)amide is relatively low, at about 40%. Sodium bis(trimethylsilyl)amide has an FT-IR spectrum with peaks at 2800 cm-1 and 1690 cm-1. The group p2 on the periodic table indicates it is an alkali metal salt, which makes it soluble in water. In order to make this compound, anhydrous acetonitrile must be used as the solvent during the reaction process. Hydrogen
