Chloryl fluoride

Chloryl fluoride is colorless as a gas and liquid, and white as a solid. It is stable under normal conditions and some of its physical properties are summarized in Table XIV. Although precise measurements of some... 

Chloryl fluoride is stable at ambient temperature in well-passivated and dry containers. Its thermal decomposition in quartz was studied by Schumacher et al. 24, 137). It reaches a measurable rate only above 300°C. The decomposition reaction is monomolecular and its rate is pressure-dependent. The actiyation energy was calculated to be 45 2 kcal mole and the rate constant was determined as = 2.3 x 10 X sec . The following decomposition mechanism was...

Chloryl fluoride is a fluorinating agent and a moderately strong oxidizer. Thus it can fluorinate AsFs to the pentafluoride (294) ... 

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 is slightly less volatile than CIF3O2, and, therefore, most of it can be removed from CIF3O2 by fractional condensation in a —112°C trap. The remaining FClOg, however, has to be removed by complexing with BFg ...

Several oxo-fluorides are known. ClOg reacts with Fg to give chloryl fluoride, ClOgF (Schumacher, 1956). The compound is produced by the action of BrFg on potassium chlorate ... 

The addition of phosphorus trichloride to olefins in the presence of per-chloryl fluoride (36) has been further studied. The olefinic component of... 

Synthetic Methods.— Direct routes to phosphonic acid derivatives from olefins and phosphorus halides continue to be explored. In the presence of oxygen, phosphorus tribromide reacts with olefins by a radical mechanism in a manner analogous to the corresponding chloride, giving 2-bromoalkyl-l-phosphonyl dibromides. The reaction of phosphorus trichloride and per-chloryl fluoride with hex-1-ene gives moderate yields of (55), the direction of... 

A number of fluorothiophenes have been prepared by the action of per-chloryl fluoride on thienyllithium derivatives, which were obtained from the corresponding bromothiophenes by metal-bromine exchange with ethyllithium.60...

Chloryl fluoride, FCIO2, is a colourless gas (bp 267 K) and can be prepared by reacting F2 with CIO2. It hydrolyses to HCIO3 and HF, and acts as a fluoride donor towards SbFs (equation 16.50) and a fluoride acceptor with CsF (equation 16.51).
