Bromotrimethylsilane can protect or deprotect functional groups selectively, act as silane blocking agent, which is widely used in the syntheses of drugs.

Chemical Properties

Clear yellow liquid

Uses

Adefovir intermediate

Uses

Powerful silylating agent

Purification Methods

Purify it by repeated fractional distillation and store it in sealed ampoules in the dark. [McCusker & Reilly J Am Chem Soc 75 1583 1953.] Also fractionate it through a 15-plate column (0.8 x 32cm packed with 1/16in single turn helices of Pt-Ir wire). [Gilliam et al. J Am Chem Soc 68 1161 1946, Pray et al. J Am Chem Soc 70 433 1948, Beilstein 4 IV 4008.]
