Bis(pentafluorophenyl)phosphorus cyanide, also known as (C6F5)2P(CN), is a phosphorus-containing organometallic compound characterized by its two pentafluorophenyl groups and a cyanide ligand. bis(pentafluorophenyl)phosphorus cyanide is of interest in the field of organophosphorus chemistry and has potential applications in the synthesis of various phosphorus-containing compounds. It is known for its stability and reactivity, which can be exploited in the formation of new chemical bonds. The strong electron-withdrawing nature of the pentafluorophenyl groups influences the reactivity and electronic properties of the molecule, making it a valuable building block in the development of new materials and pharmaceuticals.

Check Digit Verification of cas no

The CAS Registry Mumber 6998-52-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,9 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6998-52:
(6*6)+(5*9)+(4*9)+(3*8)+(2*5)+(1*2)=153
153 % 10 = 3
So 6998-52-3 is a valid CAS Registry Number.

Some Novel Phosphoranides containing Pentafluorophenyl Groups

Ali, Rusmidah,Dillon, Keith B.

, p. 2593 - 2596 (2007/10/02)

Several novel phosphoranides containing pentafluorophenyl groups, of formulae - (X= Cl, Y= Cl, Br, or I; X= Br, Y= Br or I; X= NCS, Y= Cl, Br, I or NCS) or - (X= Cl, Y= Cl, Br, or I; X= Br, Y= Br or I; X= CN, Y= Cl, Br, I, or NCS) have been identified in solution by means of 31P n.m.r. spectroscopy.Most of the species have been isolated as salts with tetra-alkylammonium ions, and further characterised by elemental analysis and (in some cases) i.r. spectroscopy.These ions -> represent the first simple phosphoranides with an organo-group attached to phosphorus and no cyano-groups present.The species with two pentafluorophenyl groups are the first phosphoranides with two organo-groups directly bound to phosphorus.No acceptor properties towards halide ions were shown by P(CCl3)Cl2 or P(C6F5)2(NCS).
