Unprecedented zwitterion in quinonoid chemistry
Siri, Olivier,Braunstein, Pierre
, p. 208 - 209 (2002)
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
Novel "Potentially Antiaromatic", Acidichromic Quinonediimines with Tunable Delocalization of Their 6π-Electron Subunits
Siri, Olivier,Braunstein, Pierre,Rohmer, Marie-Madeleine,Benard, Marc,Welter, Richard
, p. 13793 - 13803 (2007/10/03)
We present a novel family of "potentially antiaromatic" alkyl-substituted p-benzoquinonediimine pH-dependent chromophores. It appears from the structural data that these overall 12π-electron molecules should be better considered as constituted by two chem
First binuclear complex of an N,N',N'',N'''-tetraalkyl 2,5-diamino-1,4-benzoquinonediimine
Siri,Braunstein
, p. 2223 - 2224 (2007/10/03)
A new method for the synthesis of N,N',N'',N'''-tetraalkyl 2,5-diamino-1,4-benzoquinonediimines is described together with the structure of a binuclear Pt(II) complex with such a bridging ligand which provides an extended π-system.
