Chloryl fluoride oxyfluoride

Chloryl fluoride, like most of the other known chlorine fluorides and oxyfluorides, possesses amphoteric character. Owing to its weak and polar (p—jr )a Cl—F bond (see Section II, C), it exhibits a much stronger tendency to form adducts with Lewis acids than with Lewis bases. The adducts with Lewis acids result in salts containing ClOg" cations, and those with bases result in ClOgFj" salts. Both ions are discussed in detail in Sections III, G and H, respectively. 

Chloryl fluoride can be prepared in high yield by the action of CIF3 on NaClOs. It is a colorless gas and a powerful oxidizing and fluorinating agent. " " It is the most common chlorine oxyfluoride and is typically encountered in reactions between CIF and oxides or hydroxides. 

Chloryl fluoride is the most common chlorine oxyfluoride. It is always encountered in reactions of chlorine mono-, tri-, or pentafluorides with oxides, hydroxides, or poorly passivated surfaces. It was first obtained in 1942 by Schmitz and Schumacher by the reaction of CIO2 with Fj. Other methods involve the reaction of KCIO3 with either Brp3 or ClFj. The simplest method involves the reaction of NaClOj with CIF3, resulting in the highest yields and products that can readily be separated.
