INVESTIGATION OF THE REACTION BETWEEN DIALKYLPHOSPHINE OXIDES AND CARBONTETRACHLORIDE

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.
