General description
Phosphorus pentachloride is a light yellow colored phosphorous halide. It participates in the synthesis of thiazoline analogs.
Application
Phosphorus pentachloride may be used in the synthesis of following compounds:
Phosphorus pentachloride may be used as halogenating reagent to convert any substituted aldehyde into the corresponding vinyl halide. It can also undergo reaction with ammonium chloride to yield linear phosphazenes and cyclophosphazenes.
- benzenesulfonyl chloride
- malonic dinitrile
- aromatic sulfonyl chlorides
