methyl(diphenyl)phosphane oxide - Introduction
Methyl diphenyl phosphate oxide is an organophosphorus compound with the chemical formula C13H11OP. It is colorless to light yellow solid and has a weak aromatic odor.
Methyl diphenyl phosphate oxide is mainly used as a ligand, Catalyst or intermediate in organic synthesis. It can be used to catalyze a variety of organic reactions, such as asymmetric hydrogenation, catalyst-catalyzed oxidation reactions and catalyst preparation. It can also be used as a stabilizer for metal organic compounds and as an environmental catalyst.
The preparation of Methyl diphenyl phosphate oxide can be prepared by the methylation reaction of diphenyl phosphate. The specific step is to react diphenyl phosphate with Methyl iodide to obtain methyldiphenylphosphine, which is then oxidized to Methyl diphenyl phosphate oxide under the catalysis of an oxidant.
Methyl diphenyl phosphate oxide needs to be safe during use and storage. It is irritating and may be harmful to the eyes, skin and respiratory tract. Wear appropriate protective measures when using, avoid direct contact with skin and eyes. During storage, it should be sealed and kept in a cool, dry and well-ventilated place, away from fire and oxidizing agents.
