Methyldiphenylphsphine - Introduction
Methyldiphenylphosphine(Member phosphorus) is an organophosphorus compound with the chemical formula C6H5P(CH3)2. The following is a description of the nature, use, formulation and safety information of methyldiphenylphosphines:
Nature:
Methyldiphenylphosphine is a colorless liquid with a pungent odor. It is soluble in organic solvents such as ethanol, diethyl ether and dichloromethane. In air, light and high temperature conditions, Methyldiphenylphosphine will gradually oxidize.
Use:
Methyldiphenylphosphine is widely used in organic synthesis. It can be used as a catalyst, ligand or intermediate to participate in a variety of organic reactions, such as carbonyl addition, alkylation of olefins and aromatic compounds and other reactions. In addition, methyldiphenylphosphines can also be used in heteroatom chemistry and in the synthesis of organic optoelectronic materials.
Method:
Methyldiphenylphosphine is usually obtained by the reaction of phosphorus with methyl chloride. The specific method can be adding phosphorus to methyl chloride solution, heating reaction or using Lewis acid catalysis, etc.
Safety Information:
Methyldiphenylphosphines belong to organophosphorus compounds with certain toxicity. Use should follow the general laboratory safety procedures, wear protective gloves, goggles and laboratory coat. Avoid inhalation, ingestion or skin contact. Keep away from open flames and high temperature sources during operation. If you come into contact with this substance, rinse immediately with water and seek medical assistance.
