2.6- diphenyl- -hexafluorophosphate

Olah and coworkers56 found that treatment of dialkyl, arylalkyl and diaryl sulphides with nitronium hexafluorophosphate (or tetrafluoroborate) 32 at —78° in methylene chloride resulted in the formation of sulphoxides in moderate to high yields (Table 3). In the oxidation of diphenyl sulphide which affords diphenyl sulphoxide in 95% yield, small amounts of the ring nitration products (o- and p-nitrophenyl phenyl sulphides) were formed. However, diphenyl sulphone and nitrophenyl phenyl sulphoxide were not detected among the reaction products. 

Cram (98) using nitrosyl hexafluorophosphate or nitrous acid. Oae and his group (99) also have reported a method for the stereospecific deimination of 60 by means of elemental sulfur or diphenyl disulfide at 160°C. All these procedures give chiral sulfoxide with the same configuration at sulfur as that of the starting sulfoximides 60.

The step 1 product, bisphenol A diglycidyl dimethacrylate, ethoxylated bisphenol A dimethacrylate, triethlyene glycol dimethacrylate, bisphenol A diglycidyl dimethacrylate, and diphenyl iodonium hexafluorophosphate were mixed with diphenyl iodonium hexafluorophosphate and then heated to 85 °C for 5 minutes and mixed in a DAC 150 FV speed mixer for 1 minute at 3000 rpm. Silane-treated, nano-sized silica and zirconia particle filler were then added and the mixture reheated to 185°C for 5 minutes. It was then remixed in a DAC 150 FV speed mixer an additional 1 minute at 3000 rpm and the dental composition isolated. 

Carbosilane methacrylate oligomers were prepared in a two-step process. Initially a di-allyloxy intermediate was methacrylated using methacrylic anhydride to introduce a thermal crosslinker. Hydrosilation of this product was performed using chloroplatinic acid and sym-divinyltetramethyldisiloxane with 1,3- or 1,4-bis-dimethylsilylbenzene. The cationic photoinitiator diphenyl iodonium hexafluorophosphate was used to polymerize all blended compositions.

It has been reported that diphenyliodonium triflate reacts with the lithium enolates of some cyclic ketones in the presence of copper cyanide to yield the corresponding a-phenylated or a-diphenylated ketones.58 There has been a detailed analysis of the products of thermal decomposition of diphenyliodonium tetrafluoroborate and hexafluorophosphate salts.59... 

Diphenyl ditellurium was electrochemically reduced to benzenetellurolate in acetonitrile with sonication in anH-type cell. Tetrabutylammonium hexafluorophosphate served as the electrolyte. The cathode was a cylindrical graphite cloth and the anode a platinum grid. The cathodic solution was purged with argon. The potential had to be changed from — 1.20 to — 2.35 V during the reduction1-3. 

Benzenetellurolate, generated by electrochemical reduction of diphenyl ditellurium in a solution of tetrabutylammonium hexafluorophosphate, reacted with electrochemically partly reduced chlorobenzonitriles5 and bromobenzophenones6 to produce aryl phenyl tellurium compounds in moderate yields. The following compounds were isolated from the reaction mixtures ... 

Diphenyl Methyl Telluronium Hexaflnorophosphate8 30 g of IRA 400 resin are converted to the hexafluorophosphate form and added to 200 ml of water containing 0.2 g (0.5 mmol) of diphenyl methyl telluronium iodide. The mixture is stirred and warmed gently for 4 h, filtered, and the filtrate concentrated to give the colourless crystalline product m.p. 135°. 

Diphenylseleninium-4-yl)ethylidene]-2,6-diphenyl-4-oxo-4i/-tellurin4 0.50 g (1,4 mmol) 2,6-diphenyl-4-oxo-4/7-tellurin and 0,5 g (1.1 mmol) of 2,6-diphenyl-4-ethylseleninium hexafluorophosphate are heated in 2 ml acetic anhydride for 10 min on a steam bath. The mixture is diluted with 5 ml of acetonitrile and 40 m of diethyl ether. The product precipitates i n the form of green crystals on cooling. The crystals are isolated by filtration yield 33% m.p. 151-156°.
