“…However, the shoulders, shifted to higher wavelengths by approximately 1-6, 1-10 and 0-6 nm, respectively. The difference in the electronic spectra may also be attributed to fewer quinoneimine moieties in the polymer synthesized in the presence of organic sulphonic acid than the polymer prepared in sulphuric acid [30]. From Table 2, it is clear that an average absorption for the polymerized products obtained using both the monomers indicate the formation of copolymer (PA-POT); that is, absorption peaks for (PA-POT) copolymer are different from individual polymers PA and POT.…”

“…They are part of molecules with medicinally important properties, of molecules with structurally interesting properties, of materials with important electronic properties, and of transition metal complexes with catalytic activity. An arylnitrogen linkage is present in nitrogen heterocycles such as indoles [1,2] and benzopyrazoles, conjugated polymers such as polyanilines [3][4][5][6][7][8][9], and readily oxidizable triarylamines used in electronic applications [10][11][12][13]. The ability of aryl halides and triflates to form arylamines allows a single group to be used as a synthetic intermediate in aromatic carbon- carbon cross-coupling and amination reactions during structure-activity studies or library synthesis in drug development.…”

“…Eine Veränderung der Arylgruppe führte zu ähnlichen Ergebnissen wie eine umfassende Studie, die sich mit den elektronischen Aspekten der Bildung von C-S-Bindungen bei Eliminierungen von Sulfiden beschäftigte [Gl. (28)]. [60] (28) Abbildung 2 wiedergegebenen Meûwerte für die elektronischen Effekte bei Sulfid-und Amin-Eliminierungen waren ähnlich.…”

“…(28)]. [60] (28) Abbildung 2 wiedergegebenen Meûwerte für die elektronischen Effekte bei Sulfid-und Amin-Eliminierungen waren ähnlich. Sie zeigten, daû elektronenziehende Gruppen die reduktive Eliminierung beschleunigten und daû Substituenten mit groûen Werten für die Substituentenkonstante bezüglich des Mesomerie-Effekts, s R , die Reaktionsgeschwindigkeiten stärker beeinfluûten als Substituenten mit groûen Werten für die Substituentenkonstante bezüglich des induk-Abb.…”
