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.
