1,4-Bis(trimethylsilyl)benzene - Introduction
1,4-bis (trimethylsilyl)benzene is an organic silicon compound with the chemical formula C16H28Si2. Its molecular structure has two trimethylsilyl groups substituted for the 1,4 position of the benzene ring.
Nature:
1,4-bis (trimethylsilyl)benzene is a colorless to light yellow liquid with an aromatic odor similar to benzene. It has a low boiling point and flash point and is soluble in a variety of solvents, such as chlorinated hydrocarbons, aromatics and ethers.
Use:
1,4-bis (trimethylsilyl)benzene is widely used in organic synthesis. It is often used as a solvent or catalyst in the reaction, and is commonly used to catalyze the selective mineralization reaction of organic compounds such as alcohols, ketones and amines. It can also be used as a precursor for organic semiconductor materials for the preparation of optoelectronic devices.
Method:
1,4-bis (trimethylsilyl)benzene is usually obtained by reacting 1,4-dibromobenzene with trimethylmagnesium silicide. The reaction is usually carried out in a dry environment to avoid the influence of moisture and oxygen.
Safety Information:
1,4-bis (trimethylsilyl)benzene has low toxicity. However, it is irritating to the skin and eyes, so appropriate protective measures should be taken during operation, such as wearing gloves and goggles. During storage and handling, care should be taken to prevent contact with fire and high temperature to avoid fire or explosion. In addition, it should be stored in a cool, dry and well-ventilated place. If a spill occurs, it should be cleaned up quickly and properly disposed.
