A facile synthetic method for N-alkylated substituted benzochalcogenadiazoles is described. When treated with Meerwein salt, the 4-nitrobenzochalcogenadiazoles have undergone an N-alkylation to afford the expected salts as a mixture of two N1/N3 isomers in toluene. The regioselectivity of the alkylation reaction was then confirmed by spectroscopic data as well as theoretical calculations.

Three new α,α′-diimine ligands were synthesized based on condensation of 1,10-phenanthroline-5,6-dione with 1,2-phenylenediamine derivatives using different approaches. All compounds were fully characterized by IR, 1H and 13C NMR, UV-visible, and MS spectroscopies. We report the first example of a dipyrido[3,2-f:2′,3′-h]quinoxalino[2,3-b]quinoxaline, which exhibits a strong absorption at 430 nm and an interesting electrochemical behavior. These new molecules may have biological potential and are of synthetic and technological importance.

Three series of dimers containing pyrrolo[3,4-e][2,1,3]benzothiadiazole units have been prepared by application of the Pd-catalyzed Suzuki coupling. The dependence of the HOMO-LUMO separation on coplanarity has been evaluated by means of electronic absorption spectra and cyclic voltammetry. The pyrrole dimer 5c shows a narrow HOMO-LUMO separation owing to its intrinsically planar structure, as confirmed by 1H NMR. The Royal Society of Chemistry 2000.
