The condensation reaction of d-maltose to free radicals of the series of tris(2,4,6-trichlorophenyl)methyl (TTM) and tris(perchlorophenyl)methyl (PTM) has been described for the first time. The new persistent radicals 1 and 2 are very stable and have been characterized by EPR. Their cyclic voltammograms show a quasi-reversible process in the cathode, being reduced to the corresponding anions, with
首次描述了d-麦芽糖与三(2,4,6-三氯苯基)甲基(TTM)和三(全氯苯基)甲基(PTM)系列的自由基的缩合反应。新的持久性基团1和2非常稳定,并具有EPR的特征。它们的循环伏安图显示了在阴极中的准可逆过程,被还原为相应的阴离子,氧化还原电势分别比TTM和PTM低。它们的氧化活性与其还原电位密切相关。因此,尽管2被抗坏血酸还原,但是1保持不变。
