CAS

  • or
Triphenyl((trimethylphosphonio)methyl)phosphonium-bis(hexafluorophosphat) is a complex organic compound with the chemical formula C27H30F12P3. It is a phosphonium salt, characterized by the presence of a positively charged phosphonium group (P+). The molecule consists of a central phosphorus atom bonded to three phenyl rings and a trimethylphosphonio group, which is itself bonded to a methyl group. The compound is further complexed with two hexafluorophosphate anions (PF6-), which balance the positive charge of the phosphonium cation. Triphenyl<(trimethylphosphonio)methyl>phosphonium-bis(hexafluorophosphat) is often used in organic synthesis and as a phase-transfer catalyst due to its ability to facilitate reactions in both organic and aqueous environments.

Check Digit Verification of cas no

The CAS Registry Mumber 94477-76-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,4,7 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 94477-76:
(7*9)+(6*4)+(5*4)+(4*7)+(3*7)+(2*7)+(1*6)=176
176 % 10 = 6
So 94477-76-6 is a valid CAS Registry Number.

Preparation of Unsymmetrical Methyl/Phenylcarbodiphosphoranes Through Stepwise Synthesis or Rearrangement

Schmidbaur, Hubert,Herr, Rudolf,Zybill, Christian E.

, p. 3374 - 3380 (2007/10/02)

The bis-phosphonium salt 1,2-C6H4(PPh2Me+SO3F-)2 (8), obtained from the double quaternisation of 1,2-bis(diphenylphosphino)benzene (6) using CH3OSO2F, yields on transylidation with excess Et3P=CHMe as an unexpected rearrangement prod
