(two-electron) oxidation product (E)-ethylene-1,2-bis(3-guaiazulenylmethylium) bis(hexafluorophosphate) (14), quantitatively, and further, zinc-reduction of 14 in trifluoroacetic acid (=CF3COOH) at 0 °C for 1 h under argon reverts 4, quantitatively. Along with the above interesting results, our discovered another preparation method, spectroscopic properties, crystal structure, and electrochemical behavior
(E)-3-(3-愈创木烯基)丙烯醛(11)与(3-愈创木烯基甲基)三苯基溴化((9)在含有NaOEt的乙醇中在氩气下于25°C进行Wittig反应24小时,得到新标题(2 E, 4 E)-1,3-丁二烯衍生物4,分离出的产率为33%,在有氧条件下,在六氢磷酸(即65%HPF 6水溶液)中于四氢呋喃(= THF)中于25°C处理1 h提供了一种新的空气(两电子)氧化产物(E)-乙烯-1,2-双(3-愈创氮烯基甲基)双(六氟磷酸酯)(14),定量地还原了锌,还原了14在氩气下于0°C下于三氟乙酸(= CF 3 COOH)中还原1 h还原4。随着上述有趣的结果,我们发现了另一种制备方法中,光谱性质,晶体结构,和电化学行为4,其用作一个强大的双电子供体和受体,与先前报道的(相比ë)-1,详细记录了2-二(3-愈创氮烯基)乙烯(3)。
