Sodium bis(trimethylsilyl)amide Chemical Properties,Uses,Production

Chemical Properties

Slightly yellow to light beige crystalline powder


It is a strong base; deprotonates ketones and esters to generate enolate derivative.


Significantly accelerated the polymerization of pheneylacetylene in conjunction with rhodium (I) catalysis

Purification Methods

It can be sublimed at 170o/2mm (bath temperature 220-250o) onto a cold finger, and can be recrystallised from *C6H6 (its solubility is: 10g in 100mL at 60o). It is slightly soluble in Et2O and is decomposed by H2O. [Wannagat & Niederprüm Chem Ber 94 1540 1961.]It is available commercially under N2 in Sure/Seal bottles in tetrahydrofuran (various concentrations) and at ~0.6M in toluene. [Beilstein 4 IV 4014.]
