145964-33-6 - Introduction
(R)-2-(diphenylphosphino)-2 '-methoxy-1,1'-binaphthyl (R)-MOP, also known as (R)-BINAP, is a chiral organic molecule. Its chemical name is (1R,2R)-(-)-1,1 '-binaphthyl-2',2 "-Dibis (diphenylphosphine), and its chemical formula is C44H30OP2.
(R)-BINAP has many useful properties, including excellent solubility, thermal stability, and acid-base stability. It is a colorless crystalline solid, soluble in many organic solvents, such as ethanol, dimethylformamide and dichloromethane. It also has high optical rotation and the ability to recognize heavy metal ions.
(R)-BINAP has a wide range of applications in organic synthesis and metal-catalyzed reactions. It is often used as a chiral ligand and acts as a catalyst in asymmetric synthesis. It can form stable complexes with transition metals and catalyze various organic synthesis reactions, such as asymmetric hydrogenation, diazotization and catalytic reduction. In addition,(R)-BINAP can also be used in drug synthesis, materials science and biochemistry.
The method of preparing (R)-BINAP is relatively simple. A common preparation method is to synthesize it by an intramolecular substitution reaction, usually using binaphthyl and diphenylphosphine as starting materials, and the reaction is carried out in the presence of basic conditions. There are other methods, such as preparation using ligand exchange reactions or metal catalyzed reactions.
When using and handling (R)-BINAP, pay attention to safety and operating specifications. It is a chemical that can be harmful to humans and the environment. Appropriate protective equipment should be worn to avoid contact with skin and eyes. Follow proper laboratory procedures and regulations for waste disposal. In addition, it should be stored in a dry, cool and well-ventilated place, avoiding contact with oxygen, strong oxidants, acids and high temperatures.
