5-Chloro-2-ethoxyphenylboronic acid(Contains varying amounts of anhydride) - Introduction
Acid is an organic compound with the formula C8H10BClO3. The following is a description of some properties, uses, preparation and safety information about the compound:
Nature:
-Appearance: Colorless crystalline solid
-Melting point: about 89-92 degrees Celsius
-Soluble: Soluble in common organic solvents, such as ethanol and dimethylformamide
Use:
the acid is usually used as an intermediate in organic synthesis. Its main applications include the following:
-Ligand: It can be used as a ligand in metal-catalyzed reactions, such as copper-catalyzed C- C and C- O bond formation reactions.
-Substrate for cross-coupling reactions: It can undergo cross-coupling reactions with other compounds to form new compounds, which is beneficial to the expansion of organic synthesis.
-Drug synthesis: This compound is also used to synthesize active ingredients in drugs and pesticides.
Preparation Method:
The preparation method of calcium acid is relatively simple. A common method is to add 2-ethoxybenzene boric acid to ethanol and add cuprous chloride as a catalyst. Subsequently, copper chloride was added to the reaction as an oxidizing agent under heating. The reaction is typically carried out under an inert atmosphere such as nitrogen.
Safety Information:
The following safety measures should be observed when handling the calcium acid:
-Avoid contact with skin, eyes and respiratory tract. Appropriate protective gloves, safety glasses and masks should be worn.
-Work in a well-ventilated place during operation to prevent inhalation of harmful substances.
-If you come into contact with the compound, rinse immediately with plenty of water and seek medical assistance.
-During operation, pay attention to the source of fire, and properly store and dispose of the compound and its waste.
