Starting from a bromo triether derivative 1, we prepared a homologous pentadecaether, which is a precursor for the title pentadecaradical, by repeating twice the following twostep procedure (total of four steps): (1) Br/Li exchange followed by the ad

1,3-Connected polyarylmethyl dendritic heptaradical was prepared by the treatment of the heptaether precursor with lithium in THF followed by oxidation of the resultant carboheptaanion using iodine in THF at low temperature. The magnetization studies

Treatment of polyarylmethyl diethers with lithium metal in THF gave the corresponding carbodianions; subsequent oxidation with iodine at 180 K produced diradicals, which were studied in frozen THF solutions by SQUID magnetometry in the 2-100 K temper
