1,2- and 1,3-Bis(ketenyl)benzenes formed by double dehydrochlorination and by double Wolff rearrangement, respectively, gave ketenyl IR absorption at 2115, and 2122, and 2116 cm–1, respectively. Reaction of these bisketenes with the aminoxyl radical tetramethylpiperidin-1-yloxyl (TEMPO) ga...
This selective hybrid composite optimization furtherance is improved by adding ambipolar redox additive [2,2,6,6-tetramethylpiperidinyloxyl (TEMPO)] in H2SO4, and the same is studied by adding unipolar redox additive in the same H2SO4separately and their performances are reported as a first-...
Ionic liquidsNew spin probes bearing the 2,2,6,6-tetramethylpiperidine-1-yloxyl covalently bound to the imidazolium ion via a methylene spacer and an amide group are synthesized. If the anion is bis(trifluoromethylsulfonylimide) instead of iodide, the new spin probe has a similar structure as...
We have studied the magnetic properties of a series of 2,2,6,6-tetramethylpiperidin-1-yloxyl (TEMPO) radicals, among which eight ferromagnets and six metamagnets were found. Based on their crystal structures, a mechanism of intermolecular ferromagnetic coupling was proposed. The ferromagnetic ...
