Abstract :
An indirect electrochemical procedure involving an ex-cell two-phase process is proposed to produce dibenzonaphthyridine derivatives from 2,2-(2-nitrobenzyl)-2-substituted-acetonitriles in dichloromethane. The selective reduction of both nitro groups into amino groups using Cp2Ti+ in aqueous acidic medium avoids a cyclization of hydroxylamine intermediates as observed by direct electrolysis.
