Application

1-(Trimethylsilyl)imidazole may be used as an effective alternative to N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA) and N-methyl-N-(trimethylsilyl)trifluoroacetamide (MSTFA) for the efficient silylation of Ti-MCM-41, a titanium substituted mesoporous molecular sieve. This process enhances the hydrophobicity and catalytic activity of Ti-MCM-41 catalyst for cyclohexene epoxidation with aqueous hydrogen peroxide.

Other Notes

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