Fluorine phosphorus

Many reagents can be used to oxidatively fluorinate phosphorus(IIl) compounds, as shown in equation 14 [93, 94, 95, 96]... 

Fluorides with fluorine-phosphorus bonds also react with Lewis acids tert-Butylpentafluorocyclotriphosphazenes are arylated in the presence of aluminum chlonde [26] (equation 18)...

Fluoroolefins may be prepared by the reaction of Wittig reagents and other pho sphorus-contaimng ylides with fluorinated carbonyl compounds. (A discussion of the fluorinated Wittig reagents or other fluorinated phosphorus reagents with nonfluonnated carbonyl compounds is on page 581.) Tnphenylphosphoranes, derived from alkyltriphenyl phosphonium salts, react with 1,1,1-trifluoroacetone [3/] or other trifluoromethyl ketones [32, 33] (equation 26) (Table 10). 

NMR is one of the most important tools in structural elucidation, but since the technique cannot be hyphenated with GC like MS and FTIR and its sensitivity is poorer, it cannot always identify chemicals from high background samples. The unchallenged capability of NMR to give information on connectivity and neighboring atoms makes it a very desirable method in the analysis of chemicals related to the CWC. NMR can, for instance, normally find out the type of the carbons (methyl, ethyl, propyl, or isopropyl) directly connected to phosphorus ( H and 31P spectra) and the presence of fluorine-phosphorus fink (1H, 19F, and 31P spectra). Different 2D-NMR experiments give additional information on connected atoms. 

Organolithium compounds can also react with fluorinated phosphorus derivatives. For example, aryl(difluoio)phosphanes 18 are formed by reaction of the corresponding aiyllithium compounds with phosphorus chloride difluoridc. The overall reaction is shown in Table I. This procedure has also been extended to the preparation of several cyclopentadienyl(di-fluoro)phosphane derivatives. ...

Potassium reacts readily with all acids and with all non-metals, such as sulfur, chlorine, fluorine, phosphorus, and nitrogen. 

Bonds to Fluorine.—Phosphorus (m) Compounds. SCF wavefunctions for PF allow estimation of the dissociation enthalpy (4.7 eV), the dipole moment (0.6 D), and the P—F distance (1.58 A), etc.,261 while the emission spectra of the species produced by the action of microwave discharges on HPF2 and PF3 may be analysed in terms of the PF diatomic.262 Experimental data for the e.s.r. parameters of the PF2 radical263 and those calculated by ab initio methods264 are in good agreement.
