N,N′-Bis(2-tosylaminobenzylidene)-benzene-1,2-diamine

There are several structural differences between compound (I) and the other Schiff bases, ETS and PTS, obtained from 2-tosylaminobenzaldehyde and previously reported by groups. The rigidity introduced by the phenyl group between the imine N atoms forces the four N atoms in (I) into greater proximity than in either ETS or PTS. The extra rigidity introduced by the phenyl bridge in (I) also causes a change in the disposition of the tosyl groups with respect to that shown in the other molecules. In ETS and PTS, the tosyl groups appear in opposite positions, probably to minimize the steric hindrance, but this spatial disposition is not possible in (I) due to the greater proximity between the tosyl groups.
