Crystal Structures of para-Dinitrobenzene and para-Nitraniline

Nature, 1947
In view of the rather surprising distortions reported in the dimensions of the para-dinitrobenzene molecule1, a redetermination of this structure was recently attempted in this laboratory. The results of our preliminary two-dimensional survey did not point to a completely symmetrical molecule, but indicated that either (a) the planes of the nitro ...

The nature of para-bond and of para-coupling

Tetrahedron, 1972
Abstract The para-coupling in a number of tetracene- and anthracene-derivatives was investigated and found to be not measurable in the middle ring of these compounds. There is also no peri- and epi-coupling between meso-positions. However, there is appreciable coupling between meso- and terminal peri-positions.
