ELECTROCHEMICALLY INDUCED PROCESSES OF FORMATION OF PHOSPHORUS ACID DERIVATIVES. 4. SYNTHESIS OF TRIALKYL PHOSPHATES FROM WHITE PHOSPHORUS

Article abstract of DOI:10.1007/BF00863577

The products of electrolysis in dipolar aprotic solvents on the background of tetraethylammonium iodide in the presence of white phosphorus are trialkyl phosphite (the primary product after splitting of all the P - P bonds in the phosphoric oligomers) and triaryl phosphate.It was found that the formation of triaryl phosphate from white phosphorus proceeds by way of electrochemical reduction of pentaaroxyphosphorane - an intermediate product of the reaction of triaryl phosphite with iodine and phenol.A strong dependence of the yields and distribution of the products on the composition of the electrolyte has been observed. Keywords: white phosphorus, electrosynthesis, triaryl phosphate.
