(4-CYANO-PHENYL)-PHOSPHONIC ACID DIETHYL ESTER synthesis

14synthesis methods
-

Yield:28255-72-3 80%

Reaction Conditions:

with dichloro(2,2'-bipyridine)cobalt(II) in acetonitrile at 20;Electrolysis;Inert atmosphere;

Steps:

4.2. Preparative electrochemical syntheses

General procedure: All reactions were carried out under dry argon atmosphere. The preparative electrolysis was performed using a direct current source B5-49 in a three-electrode cell of 40mL witha separation of the anode and cathode compartments. The potential value of the working electrode was recorded using a direct current voltmeter V7-27 in relation to the Ag/AgCl (0.01 M, NaCl) reference electrode that had two sections separated with Vycor, the second one containing a saturated solution of the background salt in CH3CN. The surface area of the working platinum (Pt) U-shaped electrode amounted to 48.00 cm2. A ceramic plate with a pore size of 10 lm was used as a membrane. During the preparative synthesis, the electrolyte was continuously stirred using a magnetic stirrer with a continuous inflow of an inert gas that was run through a purification system to remove oxygen and other impurity gases. A platinum grid served as a cathode, and the catholyte was a saturated solution of Et4NBF4 supporting electrolyte in the corresponding solvent.
