ELECTROCHEMISTRY OF 7-CARBOETHOXYCYCLOHEPTATRIENE AND ITS AZA-ANALOGS- RING CONSTRUCTION OF AZEPINE DERIVATIVES TO ANILINE DERIVATIVES BY OXIDATION AND N-N BOND RUPTURE OF DIAZEPINE DERIVATIVES TO 1-AMINO-4-CYANO-1,3-BUTADIENE DERIVATIVES BY REDUCTION

Electrochemical reduction or oxidation of 7-ethoxycasbonylcycloheptatr iene afforded 2-ethoxycarbonylcycloheptatriene and ethyl phenylacetate , respectively. N-Alkoxycarbonyl-1H-azepine formed N-alkoxycarbonylani line in electrochemical oxidation vis a ring contruction. N-Alkoxycarb onyl-1H-1,2-diazepine afforded N-Alkoxycarbonyl-1-amino-4-cyano-1,3-bu tadiene in electrochemical reduction via an N-N bond fission.
