, p. 12246 - 12256 (2003)
A straightforward synthesis of the zwitterionic benzoquinonemonoimine 8 is reported. This molecule is a rare example of a zwitterion being more stable than its canonical forms. It is shown that 8 is best described as constituted of two chemically connecte
Unprecedented zwitterion in quinonoid chemistry
Siri, Olivier,Braunstein, Pierre
, p. 208 - 209 (2007/10/03)
The first 12π-electron zwitterionic structure in quinonoid chemistry is described with the N,N,O,O -molecule 6 in which the positive charge is π-delocalized between the nitrogen atoms and the negative charge between the oxygen atoms; depending on the crys
