Lithium phenylacetylide solution - Introduction
LITHIUM PHENYLACETYLIDE is an organic compound with the chemical formula C8H5Li. Its properties are as follows:
1. Appearance: LITHIUM PHENYLACETYLIDE is a colorless to pale yellow solid, the common form is crystalline powder.
2. Melting point: LITHIUM PHENYLACETYLIDE has a lower melting point, about 70-74 degrees Celsius.
3. Solubility: It is soluble in non-polar solvents such as ether, benzene and carbon disulfide.
The main uses of LITHIUM PHENYLACETYLIDE include the following:
1. Organic Synthesis: LITHIUM PHENYLACETYLIDE is an important reagent in organic synthesis, which can be used to synthesize various organic compounds, such as ketones, nitriles, alcohols, aldehydes, etc. It is commonly used for Lewis base reactions and Michael additions.
2. As a catalyst: LITHIUM PHENYLACETYLIDE can also be used as an alkaline catalyst to participate in some organic reactions, such as the coupling reaction of anhydride and amine.
There are many preparation methods for LITHIUM PHENYLACETYLIDE, one of which is a common preparation method as follows:
The reaction of phenylacetonitrile (C8H7N) and LITHIUM (Li) in carbon disulfide (CS2), heating to reflux, the reaction produces LITHIUM PHENYLACETYLIDE precipitate. The precipitate is then washed and dried with anhydrous ether or other non-polar solvents to obtain a higher purity LITHIUM PHENYLACETYLIDE.
LITHIUM PHENYLACETYLIDE needs to pay attention to the following safety matters during operation:
1. Because LITHIUM PHENYLACETYLIDE reacts with water to produce flammable gas, it should be kept away from water sources and humid environments during operation and storage.
2. Wear appropriate personal protective equipment, including gloves and safety glasses, to avoid contact with skin or eyes.
3. LITHIUM PHENYLACETYLIDE is a strong alkaline compound, and contact with acidic substances should be avoided to avoid dangerous reactions.
4. In the use or storage of LITHIUM PHENYLACETYLIDE, should maintain good ventilation, to avoid the accumulation of harmful gases.
Please note that LITHIUM PHENYLACETYLIDE is a toxic compound and must be operated under suitable laboratory conditions and strictly follow safe operating procedures.
