Abstract

A three-step synthesis of several di-ortriamino-m-terphenyls19–23 from 3-or 4- nitrobenzylidene-malonodinitriles1 and 1-[3-or 4-nitro (or amino) phenyl] ethylidenemalonodinitriles2 is reported. Gewald's method was applied for a one-pot preparation from1 and2 of 5′-amino [1, 1′: 3′, 1 ″-terphenyl]-4′, 6′-dicarbonitriles5– 15 which bear the nitro or amino/nitro groups on the side rings of the terphenyl system.
