1,3-Di-tert-butyl-1,3-dihydro-2H-imidazol-2-ylidene - Introduction
1, is a stable organic compound with the following properties:
1. Appearance: colorless crystal or solid.
2. Melting Point: about 139-140 ° C.
3. Solubility: soluble in organic solvents, such as ether, chloroform, insoluble in water.
4. Stability: stable at room temperature, not easy to decompose.
It has many applications in the field of chemistry:
1. Metal catalyst: can be used as a ligand for metal-catalyzed reactions, such as cross-coupling reactions, hydrogenation reactions, etc.
2. Organic synthesis: It can be used to synthesize organic compounds with a wide range of biological activities.
3. Functional Materials: can be used to prepare polymers and coatings with special properties.
There are generally two common methods of preparation:
1. Synthesized by the Haber-Wegener reaction of secondary amines. The imine compound is first prepared by reacting t-butyl ammonia and methyl methacrylate, and then subjected to a deprotection reaction to produce the target compound.
2. Through the debromination of tertiary acid salt synthesis. First, the tertiary acid salt is prepared by the reaction of tert-butyl magnesium bromide and malonate, and then the target compound is generated by nucleophilic substitution reaction.
For safety information, please note the following:
1.1 is an organic compound with potential toxicity. Appropriate protective equipment, such as gloves, glasses and laboratory coats, should be worn during use.
2. Avoid contact with skin and eyes. Immediately after contact, rinse with plenty of water.
3. Avoid inhalation of its vapor or dust. Good ventilation should be maintained during operation.
4. Storage should be sealed, in a cool and dry place to avoid light preservation.
5. Carefully read and follow the relevant safety instructions and operating procedures before use.
Please note that these are only general summaries of the nature, use, formulation and safety information that will need to be evaluated in detail depending on the specific application and experimental conditions.
