Triphenyl(benzyl)phosphonium - Introduction
(English name is called iodide) is an organic compound with the chemical formula C19H16IPH2. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: Colorless crystalline solid.
-Solubility: It dissolves well in polar organic solvents such as alcohols, ketones and ethers, but is substantially insoluble in non-polar solvents such as hydrocarbons.
Use:
-is a common reagent in organic synthesis, commonly used in phosphating reactions and nucleophilic substitution reagents in reactions.
-It can be used to introduce nucleophiles into organic molecules, thereby realizing the functional transformation of compounds.
-Also commonly used in catalytic reactions and anion-generating reactions in organic synthesis.
Method: The preparation of
-phosphonium is usually obtained by reacting triphenylphosphine and benzyl chloride (or bromide) in the presence of iodide.
Safety Information:
-It is relatively stable at room temperature, but it is necessary to avoid prolonged exposure to the sun to prevent its decomposition.
-Observe safe operating procedures and wear appropriate personal protective equipment, such as gloves, glasses and protective clothing.
-Avoid inhaling its gas or vapor to avoid respiratory irritation.
-Avoid contact with strong oxidants to avoid dangerous substances.
-When in contact with skin or eyes, rinse immediately with plenty of water and seek medical help.
-Waste disposal shall comply with local environmental regulations and shall not be dumped at will.
