Sodium bis(trimethylsilyl)amide, 98%

Description

CAS: 1070-89-9 | C6H18NNaSi2 | 183.377 g/mol

Sodium bis(trimethylsilyl)amide is used as a base in organic synthesis as well as to deprotonate other compounds containing weakly acidic O-H, S-H, and N-H bonds. It is used to prepare amines by reacting with alkyl halides. It finds application in certain organic reactions viz. generation of carbenes by dehydrohalogenation of halocarbons and Wittig reagents by deprotonation of phosphonium salts. It accelerates the polymerization of pheneylacetylene in conjunction with rhodium(I) catalysis. Furthermore, it is used for the preparation of lanthanide complexes.
