Keto-enol tautomerism in the electrochemical reduction of PARABANIC ACID (cas 120-89-8)
-
Add time:09/05/2019 Source:sciencedirect.com
Convolution potential sweep voltammetry has been applied to the electrochemical reduction of parabanic acid in the 10–100 V/s scan rate range. The overall reduction corresponds to a quasireversible two-electron, two-proton transfer to give an enediol intermediate compound. This compound undergoes an enol-keto transformation in a following homogeneous chemical reaction. This chemical reaction appears to be acid-base catalyzed in the 2 M-4×10−3 M H+ concentration range. The catalytic and electrochemical constants were determined.
