- A new method for the selective amination of 1,3- and 1,4-dinitrobenzenes and protected nitroanilines leading to polyfunctional 1,3- and 1,4-disubstituted anilines
-
The addition of functionalized arylmagnesium reagents to dinitrobenzenes and protected nitroanilines at -20°C in THF furnishes after a reductive workup polyfunctional diarylamines in 47-92% yield.

- Palladium-catalyzed synthesis of pure, regiodefined polymeric triarylamines
-
Triarylamine polymers were prepared by palladium-catalyzed amination of aryl halides, and the electrochemical and magnetic properties of these materials were studied. Through a careful evaluation of the catalytic and polymer chemistry involved in this pro

- Preparation and characterization of novel DPPH-based diradicals
-
A series of 1,1'(2,4-di-X-benzene-1,3-diyl)bis[1-(4-Y-phenyl)-2- picrylhydrazine]s were prepared an oxidized to generate the corresponding bis-DPPH diradicals. No triplet species was observed for the compounds with X = H in the ESR measurement. Modification of the central benzene ring (x = Me) and N-phenyl group (Y = OMe, P, t-Bu) allowed the detection of their triplet diradicals. Especially, the diradical with X = Me, Y = t-Bu was successfully purified, isolated at O aC as a purple solid, and was shown to be in a triplet ground state.
