Pentafluorophenyl dichlorophosphine, also known as (C6F5)PCl2, is an organophosphorus compound characterized by a pentafluorophenyl group (C6F5) bonded to a dichlorophosphorus (PCl2) moiety. This chemical is a colorless, volatile liquid with a pungent odor and is highly reactive due to the presence of the dichlorophosphorus group. It is used as a reagent in organic synthesis, particularly in the formation of phosphorus-containing compounds and as a ligand in transition metal complexes. Due to its reactivity, it requires careful handling and is typically stored under an inert atmosphere to prevent unwanted reactions.

5032-91-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5032-91-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,3 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5032-91:
(6*5)+(5*0)+(4*3)+(3*2)+(2*9)+(1*1)=67
67 % 10 = 7
So 5032-91-7 is a valid CAS Registry Number.

Synthesis of 18F-radiolabeled organophosphine fluorides for thiol-chemoselective peptide conjugation

Zhuang, Huanglan,Guo, Zhide,Zhuang, Rongqiang,Zhang, Xianzhong

, p. 597 - 607 (2020/10/14)

Two 18F-radiolabeled organofluorophosphine fluorides ([18F]4 and [18F]7) for chemoselective thiol-conjugation were designed and synthesized via 18F–19F isotopic exchange reaction. This simple and rapi

Synthesis and characterization of some perfluorophenylphosphine derivatives

Magnelli,Tesi,Lowe Jr.,Mcquistion

, p. 457 - 461 (2008/10/08)

Bis(pentafluorophenyl)chlorophosphine and pentafluorophenyldichlorophosphine are prepared in good yields from pentafluorophenylmagnesium bromide and phosphorus trichloride. The reactions of the halophosphines with the Lewis bases water, ammonia, dimethylamine, and 2-methylaziridine produced substituted phosphines. Oxidative chlorination of bis(pentafluorophenyl)phosphinamide followed by dehydrohalogenation gave perfluorophenylphosphonitriles. The infrared and pertinent proton magnetic resonance spectra of these compounds are discussed.
