PHOSPHORUS OXYCHLORIDE: SYNTHESIS AND REACTIVITY

Phosphorus oxychloride POCl₃ is a versatile reagent widely employed in organic synthesis. Its preparation involves the reaction of phosphorus trichloride PCl₃ with oxygen dioxygen at elevated temperatures. This exothermic process results in the formation of POCl₃ along with hydrochloric acid HCl. The resulting product, a colorless to yellow l
