title: Studies on the polarographic reduction of the azomethine bond in the products of beta-keto-esters coupled with aryldiazonium chlorides.
abstract: The products of coupling beta-keto-esters with aryldiazonium chlorides have been studied polarographically and give a single well-defined 4-electron diffusion-controlled irreversible wave in the pH range 2.0-11.0. The effect of electron-donating and electron-withdrawing substituents and the correlation between the half-wave potential and Hammett substituent constant have been studied.
