- W2164336502 abstract "Die chemischen und spektroskopischen Eigenschaften der Titelverbindungen werden beschrieben. tert.-Butylgruppen erhöhen die Stabilität der 9-Carbazolyl-Radikale und der Carbazol-Radikalkationen: 1.3.6.8-Tetra-tert.-butyl-9-carbazolyl (10) ist eine stabile kristallisierte Substanz. Größen und Vorzeichen der ESR-Kopplungskonstanten von 10 wurden aus den ESR-, 1H-NMR- und 2H-NMR-Spektren erhalten. Verschiedene Radikal-Dimere wurden isoliert und identifiziert. Eines dieser Dimeren (13) besitzt eine Struktur, die der Konstitution des Triphenylmethyl-Dimeren sehr ähnlich ist. Aminyls, 6. tert-Butyl-Substituted 9-Carbazolyl Radicals, Carbazol Radical Cations and Carbazol-9-oxyl Radicals Chemical and spectroscopic data for the title compounds are reported. tert-Butyl groups increase the stability of 9-carbazolyl radicals and carbazol radical cations: 1.3.6.8-tetra-tert-butyl-9-carbazolyl (10) is a stable crystalline solid. The magnitudes and signs of the e.s.r. coupling constants in 10 were evaluated from the e.s.r., 1H n.m.r. and 2H n.m.r. spectra. Various radical dimers were isolated and identified. One of these dimers (13) has a structure similiar to that of the triphenylmethyl dimer." @default.
