Tetraethyl (3,3,4,4,5,5-hexafluorocyclopent-1-ene-1,2-diyl)bis(phosphonate) is a complex organic compound with the chemical formula C14H20F6O4P2. It is a colorless liquid at room temperature and is soluble in organic solvents. tetraethyl (3,3,4,4,5,5-hexafluorocyclopent-1-ene-1,2-diyl)bis(phosphonate) is characterized by its hexafluorocyclopent-1-ene-1,2-diyl backbone, which is a cyclic structure with six fluorine atoms, and two phosphonate groups attached to it. The phosphonate groups are derived from phosphoric acid, where each phosphorus atom is bonded to two oxygen atoms and two ethyl groups. tetraethyl (3,3,4,4,5,5-hexafluorocyclopent-1-ene-1,2-diyl)bis(phosphonate) is used in various applications, including as a flame retardant, a plasticizer, and a stabilizer in the production of polymers. It is also known for its thermal stability and resistance to hydrolysis, making it a valuable component in industrial chemical processes.

4655-86-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4655-86-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,5 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4655-86:
(6*4)+(5*6)+(4*5)+(3*5)+(2*8)+(1*6)=111
111 % 10 = 1
So 4655-86-1 is a valid CAS Registry Number.

Synthesis of trans-1,2-difluoroethenediylbis(phosphonic acid) and other unsaturated phosphonic acids

Su, Debao,Guo, Cai-Yun,Willett, Roger D.,Scott, Brian,Kirchmeier, Robert L.,Shreeve, Jean'ne M.

, p. 3152 - 3155 (2007/10/02)

The phosphonic acids (HO)2P(O)CF=CFP(O)(OH)2, CF2=CFCH2CH2P(O)(OH)2, and (HO)2P(O)C=CP-(O)(OH)2(CF2)nCF 2 (n = 1, 3) have been synthesized for the first time. trans-1,2-Difluoroethenediylbis(phosphonic acid) was prepared from (C2H5O)2P(O)CFBrCFBrP(O)(OC2H 5)2, which had been obtained via coupling of the corresponding sulfinate salt, (C2H5O)2P(O)CFBrSO2Na, by adding 30% aqueous hydrogen peroxide to a solution Of(C2H5O)2P(O)CFBrSO2Na and iron(II) sulfate. The X-ray crystal structure of the salt [Zn(H2O)6]2+[O(HO)P(O)CF=CFP(O)(OH)O] 2- indicates a network of [Zn(H2O)6]2+ dications and the acid dianions linked together with water molecules via hydrogen bonding. The phosphorus, fluorine, and carbon atoms are coplanar.
