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.
