일반 설명

for synthesis

애플리케이션

Phosphorus trichloride (PCl₃) can be used as:

• A chlorinating agent for the alcohols, aldehydes, ketones, and carboxylic acids.
• A reagent to convert alcohols, diols, and phenols to phosphites.
• A reducing agent to reduce sulfoxides, amine N-oxides, and hydroxy amides to corresponding sulfides, amines, and amides.

It can also be used as a reagent to synthesize:

• Phosphaindolizines and thiazolodiazaphospholes by reacting with quaternary ammonium salts.
• Phosphorus-containing ligand molecules via the introduction of the phosphorus atom.
• Benzidronate by treating with phenylacetic acid and phosphorous acid in methanesulfonic acid, followed by hydrolysis.
