Trimethylsilylmethyltrifluoromethanesulfonate - Introduction
Trimethylsilylmethyltrifluoromethanesulfonate is an organic compound with the chemical formula (C3H9Si) (CF3SO3), often abbreviated as TMSOTf. The following is a description of its nature, use, preparation and safety information:
Nature:
TMSOTf is a colorless to slightly yellow liquid that is volatile at room temperature. It has high thermal and chemical stability and can be used under a wide range of reaction conditions. It is stable in air, but sensitive to water and moisture.
Use:
TMSOTf is widely used in organic synthesis. Its main uses include:
1. as a conversion reagent: TMSOTf can convert compounds such as alcohols, acids and amines into corresponding sulfonates, esters and amides.
2. As a catalyst: TMSOTf can be used as an acid catalyst in many chemical reactions, such as Marchin blocking reaction and disease acylation reaction.
3. As an activator: TMSOTf can activate halogenated hydrocarbons and boric acid esters and other substrates to promote their reactions with other compounds.
Preparation Method:
Generally, the method for preparing TMSOTf is to first synthesize sulfonyl fluoride (SO2F2), and then react with methyl trifluoromethane thiol (CF3SH) to obtain TMSOTf. The preparation process requires attention to the safety of operating conditions and the toxicity of gaseous sulfonyl fluoride.
Safety Information:
TMSOTf is a corrosive compound that requires the use of protective gloves, goggles, protective clothing, etc. It is irritating to the skin and eyes and may have adverse health effects when inhaled or ingested. Contact with water and moisture should be avoided during use. Storage should be sealed, in a well-ventilated place away from fire and sparks. When handling and disposing of waste, it should be handled in accordance with relevant regulations.
