Trichlorobis(pentafluorophenyl)phosphorane, also known as (C6F5)2PCl3, is a phosphorus-based organometallic compound characterized by its two pentafluorophenyl groups and three chlorine atoms. This colorless, crystalline solid is a highly reactive and moisture-sensitive reagent, often used in organic synthesis as a Lewis acid and a phosphorus(III) chloride source. It is particularly effective in promoting Friedel-Crafts reactions, where it acts as a catalyst to facilitate the electrophilic substitution of aromatic compounds. Due to its high reactivity, it is crucial to handle Trichlorobis(pentafluorophenyl)phosphorane with care, typically under an inert atmosphere or in a dry box, to prevent unwanted side reactions.

6779-72-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6779-72-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,7 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6779-72:
(6*6)+(5*7)+(4*7)+(3*9)+(2*7)+(1*2)=142
142 % 10 = 2
So 6779-72-2 is a valid CAS Registry Number.

The Acceptor Properties of some Pentafluorophenylphosphorous(V) Species

Ali, Rusmidah,Dillon, Keith B.

, p. 1375 - 1381 (2007/10/02)

The acceptor properties of P(C6F5)nCl5-n (1 + (1 + towards Lewis bases, such as the chloride ion and uni- and bi-dentate pyridines, have been investigated.Several new complexes have been isolated, and characterised by elemental analysis and (in some cases) 31P n.m.r. and/or i.r. spectroscopy.
