Bis(4-fluorophenyl)iodonium bromide is a chemical compound with the formula C12H8BrF2I+. It is an organoiodine compound that features two 4-fluorophenyl groups bonded to an iodine atom, which is further connected to a bromide ion. bis(4-fluorophenyl)iodonium bromide is often used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the promotion of various types of coupling reactions. It is known for its ability to act as a mild oxidant and as a source of electrophilic iodine, making it a valuable tool in the synthesis of complex organic molecules. The compound is typically handled with care due to its sensitivity to light and moisture, and it is often stored under an inert atmosphere to maintain its stability.

Check Digit Verification of cas no

The CAS Registry Mumber 1868-08-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,6 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1868-08:
(6*1)+(5*8)+(4*6)+(3*8)+(2*0)+(1*8)=102
102 % 10 = 2
So 1868-08-2 is a valid CAS Registry Number.

A mild carbon-boron bond formation from diaryliodonium salts

Miralles,Romero,Fernández,Mu?iz

supporting information, p. 14068 - 14071 (2015/09/15)

The direct metal-free borylation of diaryliodonium salts with diboron reagents is now demonstrated to be a feasible process toward formation of aryl boronic esters without any additive or catalysts, and it can be extended to a two-step C-C coupling of both aryl groups of the initial diaryliodonium reagent.

Facile syntheses of symmetrical diaryliodonium salts from various arenes, with sodium metaperiodate as the coupling reagent in acidic media

Kraszkiewicz, Lukasz,Skulski, Lech

experimental part, p. 2373 - 2380 (2009/04/14)

An easy, inexpensive, safe, and effective preparative procedure to obtain symmetrical diaryliodonium bromides (in 17-88% crude yields) from various arenes is presented in this paper. A novel method for the in situ preparation of iodosyl sulfate (Chretien's reagent) is given. Eleven exemplary crude diaryliodonium bromides were readily oxidatively metathesized with 40% aqueous tetrafluoroboric acid and 30% aqueous hydrogen peroxide (in boiling acetone, used both as a solvent and 'halogen scavenger') to give pure diaryliodonium tetrafluoroborates in 15-85% yields.
