Triose reductone (2,3-dihydroxy-2-propenal) was oxidized by Cl2−·, Br2−·, (SCN)2−·, and N3· to produce a triose reductone radical which had an absorption maximum at 398 nm, ε=5500 M−1 cm−1 (1 M=1 mol dm−3) and decayed by second-order kinetics. The rate constants for the reactions of triose reductone with these oxidizing inorganic radicals were obtained. The pKa of this radical was found to be 1.4.
三糖还原酮(2,3-二羟基-2-
丙烯醛)被 Cl2-、Br2-、(SCN)2-和 N3-氧化生成三糖还原酮自由基,该自由基在 398 nm 处有最大吸收,ε=5500 M-1 cm-1 (1 M=1 mol dm-3),并按二阶动力学衰减。得出了三糖还原酮与这些氧化性无机自由基反应的速率常数。该自由基的 pKa 值为 1.4。
