Vinyldiphenylphosphine - Introduction
diphenylvinylphosphine(diphenylvinylphosphine) is an organophosphorus compound with the chemical formula C14H11P. It is a colorless to yellow solid, commonly in the form of crystals. The compound is insoluble in water at room temperature, but readily soluble in most organic solvents.
The main use of diphenylvinylphosphine is as a ligand to participate in the synthesis and catalytic reactions of metal organic compounds. It is widely used in organic synthesis reaction of cross coupling reaction, reduction reaction, oxidation reaction, etc. In addition, diphenylvinylphosphine is also used as a stabilizer, catalyst and dye synthesis intermediate.
The preparation method of diphenylvinylphosphine is usually completed by Grignard reaction or Sonogashira Reaction. Among them, the Grignard reaction is the condensation of diphenylphosphine with aldehyde, and then the dehydration reaction is carried out to obtain diphenylvinylphosphine. The Sonogashira Reaction is the reaction of dichloroethylene with phenyl bromide, and then with diphenyl phosphine in the presence of copper catalyst to obtain diphenylvinylphosphine.
Regarding safety information, diphenylvinylphosphate has no serious harm to the human body and the environment under normal operating conditions. However, as an organophosphorus compound, it may have some acute toxicity and irritation. Therefore, care should be taken to avoid skin contact, inhalation or ingestion during use, and to ensure good ventilation conditions. During disposal, the relevant safety regulations should be observed and attention should be paid to the correct disposal of waste.
