Réduction électrochimique directe et indirecte des N-arylsulfonyl-N-phényl hydrazonates
Written by sctunisie no commentsCathodic reduction of several N-Arylsulfonyl-N-phényl hydrazonates of a typical structure (schemel) has been investigated by cyclic voltammetry and controlled potential electrolysis at mercury electrode in aprotic solvent. Quantitative results for preparative electrolysis show the occurrence of reductive cleavage of the carbon-sulfur bond leading to the formation of N-phenylhydrazonates in good yields. For all the investigated compounds values of the kinetic solution electron transfer are reported.
