용도
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.
정의
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.
일반 설명
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.
