The reaction between Br3GeAll (1) and N(CH2CHMeOSnBu3)3 (2, mixture of isomers) yielded N(CH2CHMeO)3GeAll (3) as a mixture of diastereomers. Three azagermatranes of the type N(CH2CH2NR)3GeAll (9, R = H; 10, R = Me; 11, R = Me3Si) have been synthesized from the reaction of (Me2N)3GeAll (5) with N (CH2CH2NHR)3 (R = H, 6; Me, 7; Me3Si, 8). Composition and structures of the new compounds were established by elemental analyses, 1H and 13C NMR spectroscopy and mass spectrometry.

This paper describes the synthesis of several new series of 1-(2-aryldiazen-1-yl-) 4-arylpiperazines and 1-(2- aryldiazen-1-yl-)4-arylalkylpiperazines by using diazonium coupling between arenediazonium ions with the appropriate 1-arylpiperazine or the 1-arylalkylpiperazine. The new compounds have a common thread in that they are isomers of the series of N-(2,3-dimethylphenyl)- N’-(aryldiazenyl)-piperazines. The new triazenes have been characterized by IR and NMR spectroscopy and mass spectrometry.

Starting from the well known stable free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH; 2a) and its congener 2,2-diphenyl-1-(4-cyano-2,6-dinitrophenyl)hydrazyl 2b, or from their reduced hydrazine counterparts 1a,b, it was possible to obtain the p-quinonoid compounds 4a,b by oxidation with ceric (Ce4+) sulfate, which by reduction gave the corresponding hydroxyl derivatives 2-phenyl-2-(4-hydroxyphenyl)-1-picrylhydrazine 5a or 2-phenyl-2-(4-hydroxyphenyl)-1-(4-cyano-2,6-dinitrophenyl)hydrazine 5b. These hydroxyl derivatives (5a,b) react with 4-carboxy-TEMPO or 2,2-diphenyl-1-(4-carboxy-2,6-dinitrophenyl)hydrazine to form the corresponding esters 6a,b or 8a,b. These esters (6a,b and 8a,b) lead to the hybrid hetero diradicals (nitroxide–hydrazyl type) 7a,b or homo biradicals (hydrazyl–hydrazyl type) 9a,b by oxidation with lead dioxide or potassium permanganate. The new compounds were characterized by UV-vis, NMR, EPR, and MS analysis, and their magnetic behaviour was investigated.

ABSTRACTA series of fluorine appended highly conjugated fullerenes were prepared containing fluoro-α-cyanostilbene and aryl ester units. These modified PCBM dyads are fully characterized by NMR, Mass spectrometry, UV-vis, and cyclic voltammetry (Figures 1-4). It was found that the presence of fluoro-α-cyanostilbenes and esters affects the cyclic voltammetry and absorption in the UV-Vis region. The PCBA modified fullerenes significantly influences the HOMO-LUMO energy and wide absorption compared to PCBM.
