Autor: I. Gobel, E. Herdtweck, Christian Näther, Hans Bock
Publikováno v: Monatshefte f�r Chemie Chemical Monthly. 128:841-848
Protonation of the sterically overcrowded N,N,N′,N′-tetraisopropyl-p-phenylenediamine leads to a significant shortening of the C-N bond lengths of 7 pm as well as to a widening of the phenyl ipso-angle to 122°. All structural changes can be attr
