N-(Trimethylsilyl)imidazole Chemical Properties,Uses,Production

Chemical Properties

Colorless transparent liquid

Physical properties

bp 93–94 °C/14 mmHg; fp 5 °C; d 0.956 g cm?3.

Uses

N-(Trimethylsilyl)imidazole is a silylating agent for alcohols and 1,3-dicarbonyl compounds; reaction with esters to give imidazolides; preparation of O-trimethylsilyl monothioacetals; aromatization of the A-ring of steroids. It participates in the reactions of Hydroxyl Silylation Reactions, Silyl Aminal Formation Reactions, Nitrogen Silylation Reactions, Acyl Imidazole Formation, Michael Addition Reactions, Substitution Reactions, Phosphoroimidazolidate Formation, and other uses.

Uses

A general silylating agent, particularly for alcohols. An intermediate for the synthesis of imidazole derivatives.

Uses

N-(trimethylsilyl) imidazole (TMSim) is quite reactive with hydroxyl groups in a variety of analytes including a variety of lipids.As with other derivatization reactions,microwave heating can greatly improve process efficiency.

Uses

Silylating reagent for the protection of hydroxyl groups in the presence of amine functionalities.1

Definition

ChEBI: A member of the class of imidazoles in which the hydrogen at position 1 is replaced by a trimethylsilyl group. N-trimethylsilylimidazole is a derivatisation agent used in gas chromatography/mass spectrometry applications.

General Description

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.
