General description

Azidotrimethylsilane (TMSN3) is a a colorless and stable organosilane reagent. It shows very slow decomposition at high temperatures. It is a very commonly used azide source and has been used in the synthesis of aminotriazole ligands. Azidotrimethylsilane can be easily synthesised by adding chlorotrimethylsilane dropwise to a stirred solution of NaN3 in diethylene glycol dimethyl ether.

Application

Azidotrimethylsilane can be used as:
  • A nitrogen precursor to prepare GaN nanowire via metal-organic chemical vapor deposition method.
  • An electrolyte additive in Li-O2 batteries. The addition of TMSN3 results in the formation of robust solid electrolyte interphase.
  • An efficient reagent in the synthesis of tetrazoles, fullerenyl azide, and α-azido oximes.
  • A silylating agent in the O-trimethyl silylation of alcohols and phenols.

A cyclic (alkyl)(amino)carbene (CAAC) has been shown to react with a covalent azide similar to the Staudinger reaction. The reaction of Me CAAC with trimethylsilyl azide afforded the N-silylated 2-iminopyrrolidine (Me CAAC=NSiMe3 ), which was fully characterized. This compound undergoes

Click chemistry, and the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) in particular, is a powerful new synthetic tool in polymer chemistry and material science.

Since the preparation of the first organic azide, phenyl azide, by Peter Griess in 1864 this energy-rich and versatile class of compounds has enjoyed considerable interest.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
