Dioctylphosphinyl chloride, also known as di-n-octylphosphinoyl chloride or (C8H17)2PCl, is an organophosphorus compound characterized by its phosphorus atom bonded to two octyl groups and a chlorine atom. This colorless liquid is a valuable intermediate in the synthesis of various organophosphorus compounds, including flame retardants, pesticides, and pharmaceuticals. It is also used as a ligand in coordination chemistry. Due to its reactivity, it is essential to handle dioctyphosphinyl chloride with care, as it can be corrosive and harmful if inhaled or absorbed through the skin.

7539-86-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7539-86-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,3 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7539-86:
(6*7)+(5*5)+(4*3)+(3*9)+(2*8)+(1*6)=128
128 % 10 = 8
So 7539-86-8 is a valid CAS Registry Number.

INVESTIGATION OF THE REACTION BETWEEN DIALKYLPHOSPHINE OXIDES AND CARBONTETRACHLORIDE

Aksnes, Gunnar,Majewski, Piotr

, p. 261 - 274 (2007/10/02)

The time dependent formation of intermediates and end products in the reaction between Et2P(O)H and CCl4 is analysed using (31)P-NMR technique.The various reaction steps are studied separately in order to elucidate the overall mechanism.A key step is the disproportionation of Et2P(O)H catalysed by Et2PCl and Et2P(O)Cl, in a cyclic process, the latter being produced initially by the reaction between Et2P(O)H and CCl4.The diethylphosphine formed during disproportionation reacts immediately with CCl4, driving the reaction through the intermediates, Et2PCl and Et2PCCl3which react with Et2P(O)OH producing Et2P(O)Cl, (Et2PO)2O, and Et2P(O)CHCl2, as end products.The influence of the substituents on rate and product yields was studied with n-propyl, n-butyl, n-octyl, and allyl as substituents in the dialkylphosphine oxide.
