Chemical Properties
white to light yellow crystal powde
Uses
The reaction of (pentafluorophenyl)diphenylphosphine with C-ethoxycarbonyl-(p-methoxyphenyl) nitrile imine was used to synthesize [2,3,4,5-tetrafluoro-6-(p- methoxyphenylamino)phenyl]diphenylphosphine oxide whose reduction with trichlorosilane. the reactions of (pentafluorophenyl)diphenylphosphine and bis(penta- fluorophenyl)(phenyl)phosphine with nitrilimines (Housgen 1,3-dipoles) involves two-stage cycloaddi- tion and leads to formation of sufficiently stable fluorophosphoranes.
Check Digit Verification of cas no
The CAS Registry Mumber 5525-95-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,2 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5525-95:
(6*5)+(5*5)+(4*2)+(3*5)+(2*9)+(1*5)=101
101 % 10 = 1
So 5525-95-1 is a valid CAS Registry Number.

Preparation of diphenyl phosphide and substituted phosphines using alkali metal in silica gel (M-SG)

supporting information; experimental part, p. 1688 - 1692 (2009/09/06)
Alkali metals absorbed in silica gel (the M-SG reagents) efficiently cleave C-P bonds in triaryl- and diarylphosphines. The resulting alkali metal phosphides can serve as useful building blocks for a variety of phosphines. Alkyldiarylphosphines undergo exclusive aryl group cleavage.
