Reference

Trimethylsilylating agents are commonly used in chemical synthesis, particularly in the protection of hydroxyl, amine, and carboxyl functional groups. Here are some examples of these agents:

1. Trimethylsilyl chloride (TMSCl) - Often used to introduce trimethylsilyl groups into compounds.
2. Bis(trimethylsilyl)acetamide (BSA) - Known for its efficiency in trimethylsilylation reactions.
3. N,O-Bis(trimethylsilyl)trifluoroacetamide (BSTFA) - Widely used in gas chromatography due to its volatility and stability.
4. Trimethylsilyl trifluoromethanesulfonate (TMSOTf) - A potent silylating agent used in various organic syntheses.
5. Trimethylsilyl azide - Primarily used for the azidolysis of epoxides.
6. N,N-Bis(trimethylsilyl)urea (BSU) - Commonly used in the trimethylsilylation of alcohols.
