N,N-Dimethyltrimethylsilylamine Usage And Synthesis

Chemical Properties

clear colorless to pale yellow liquid

Uses

N,N-Dimethyltrimethylsilylamine was used in the synthesis of phosphoramidite. It was also employed as a reagent in the preparation of iminium salts and amides as well as for the silylation of polymers. A combination of N-(trimethylsilyl)dimethylamine and MeI was also effective to give p-methylbenzoic acid with a 85% yield based on 90% conversion from the corresponding Me ester. DETA has been treated with N-(trimethylsilyl)-dimethylamine to yield mono-, di- and tri- silylated derivatives
