Description

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

Human metabolism of α-pinene and metabolite kinetics after oral administration.

Lukas Schmidt et al.

Archives of toxicology, 91(2), 677-687 (2015-12-19)

We studied the human in vivo metabolism and the elimination kinetics of α-pinene (αPN), a natural monoterpene which commonly occurs in the environment. Four volunteers were exposed to a single oral dose of 10 mg αPN. Each subject provided one pre-exposure
