Descrizione

Descrizione generale

1-(Trimethylsilyl)imidazole (TMSIM) has high silyl donor ability. It does not react with amino groups and also does not help in formation of enol-ether on unprotected ketone groups. It is useful as a silylating agent for ecdysones, norepinephrine, dopamine, steroids, sugars, sugar phosphates and ketose isomers.

Powerful silylating agent, particularly for alcohols; Synthesis of acyl imidazolides

Applicazioni

1-(Trimethylsilyl) imidazole may be used for the synthesis an O-silylated derivative of a hexahomotriazacalix[3]arene. It may also be used for the silylation of Ti-MCM-41 catalyst, to study its effect on the olefin epoxidation with aqueous H₂O₂, 1-(Trimethylsilyl) imidazole was found to improve the hydrophobicity and the catalytic performance of Ti-MCM-41.
