Perchloryl fluoride

Perchloryl fluoride is a reactive gas with the chemical formula ClO3F. It has a characteristic sweet odor that resembles gasoline and kerosene. It is toxic and is a powerful oxidizing and fluorinating agent. It is the acid fluoride of perchloric acid. In spite of its small enthalpy of formation (ΔHf° = −5.2 kcal/mol), it is kinetically stable, decomposing only at 400 °C.: 380  It is quite reactive towards reducing agents and anions, however, with the chlorine atom acting as an electrophile.: 382  It reacts explosively with reducing agents such as metal amides, metals, hydrides, etc. Wikipedia
