420-52-0 Usage
General Description
Trifluoromethylphosphane, also known as CF3PH2, is a chemical compound composed of carbon, hydrogen, and phosphorus atoms with three fluorine substituents attached to the phosphorus atom. trifluoromethylphosphane is commonly used as a ligand in coordination chemistry and organometallic chemistry reactions due to its electron-donating properties and ability to form stable complexes with transition metals. Trifluoromethylphosphane can also serve as a reducing agent in various chemical reactions and as a precursor in the synthesis of other organophosphorus compounds. It is important to handle trifluoromethylphosphane with caution, as it is a potentially toxic and flammable compound that should be used in a well-ventilated area with proper safety equipment.
Check Digit Verification of cas no
The CAS Registry Mumber 420-52-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 420-52:
(5*4)+(4*2)+(3*0)+(2*5)+(1*2)=40
40 % 10 = 0
So 420-52-0 is a valid CAS Registry Number.

Diels-Alder Adducts of the Diphosphene F3CP=PCF3
Grobe, Joseph,Van, Duc Le,Schulze, Joachim
, p. 1753 - 1755 (2007/10/02)
The heterocycles 3 to 6 are formed in a one-pot procedure by reacting trifluoromethyl phosphorus diiodide F3CPI2 with tin dichloride SnCl2 in the presence of the corresponding 1,3-dienes.The reactions proceed via cycloaddition of the diphosphene intermediate F3CP=PCF3 (1) as suggested by the high yields obtained (50 to 100percent) and the formation of the cyclic tetraphosphane (F3CP)4 (2) as the only by-product.Cycloreversion occurs at moderate temperatures as demonstrated by the reaction of 6 with 2,3-dimethylbutadiene to give 3 and cyclohexadiene.The products have been characterized by NMR and mass spectra. - Key words: Perfluoromethyl Diphosphene, Preparation (in situ), Cycloaddition, Mass Spectra, NMR Spectra
