solution0.5MinTHF - Introduction
Lithium (trimethylsilyl)acetylide, also known as TMSCC-Li, are organic compounds containing lithium. The following is a description of its nature, use, preparation and safety information.
Nature:
-Appearance: The TMSCC-Li is usually a light yellow to dark yellow solid.
-Solubility: TMSCC-Li has good solubility in anhydrous organic solvents.
Use:
-As a synthetic chemical reagent, TMSCC-Li can be used in carbon-carbon bond formation reactions in organic synthesis.
- TMSCC-Li can react with halogenated hydrocarbons, nitrile compounds, esters and other substrates to generate the corresponding acetylides.
- TMSCC-Li can also be used to synthesize organometallic compounds containing alkynyl groups.
Preparation Method:
-The preparation of TMSCC-Li is generally obtained by reacting trimethylsilylacetylene with an organolithium reagent. The reaction conditions may be low temperature, such as below -78°C, to control side reactions of the reaction.
Safety Information:
- TMSCC-Li is an organometallic compound, which is dangerous. Therefore, when operating the TMSCC-Li, strict laboratory safety practices should be followed.
- TMSCC-Li will react violently when in contact with water or moisture, so avoid contact with moisture.
-Wear appropriate protective gloves and goggles during use to ensure that the operating area is well ventilated.
- TMSCC-Li should be away from high temperature, flame and oxidant, storage should be placed in a dry, ventilated place.
