The dication of 1,4,5,8-tetrakis(dimethylamino)naphthalene: properties, crystal structure and a comparison with the dication of 1,4-bis(dimethylamino)benzene
Abstract
The dication salt 4·(I3–)2 of 1,4,5,8-tetrakis(dimethylamino)naphthalene 3 is isolated and its molecular structure established by X-ray crystallographic analysis; spectral data of 4 are compared with those of the dication 2 of 1,4-bis(dimethylamino)benzene, determined in the presence of an oxidant, i.e. Br2, Ag+.
