Description

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
Sodium bis(trimethylsilyl)amide is useful for the generation of carbenes, the amination of sulfonamides, and for the preparation of lanthanide complexes. It is significantly accelerated the polymerization of pheneylacetylene in conjunction with rhodium (I) catalysis. It is used to deprotonate ketones and esters to generate enolate derivatives, phosphonium salts, generating Wittig reagents.

Solubility
Soluble in benzene, toluene and ether. Reacts with water.

Notes
Moisture Sensitive. Incompatible materials are Oxidizing agents, Oxygen. Store away from water and oxidizing agents.
