    • Dihydrophenazines and bis(dihydrophenazines) are prepared in high yield under commercially viable reaction conditions by reacting a catechol with a 1,2-diaminoaryl compound, wherein either the catechol or the 1,2-diaminoaryl compound is provided in at least 50% molar stoichiometric excess. The product may be oxidized to the corresponding phenazine, but is preferably derivatized at one or both of the 5,10-positions to form a monosubstituted or disubstituted dihydrophenazine or bis(dihydrophenazine). Most preferably, 5,10-dialkyl-5,10-dihydrophenazines are prepared starting from catechol and 1,2-diaminoaryl compound in a one pot synthesis. The products are useful as dyes, and in particular as chromophores in electrochromic systems.
    • 在商业上可行的反应条件下,通过使邻苯二酚与1,2-二氨基芳基化合物反应,以高产率制备二氢苯并嗪和双(二氢苯并嗪),其中儿茶酚或1,2-二氨基芳基化合物以至少50%的摩尔化学计量 过量。 产物可以被氧化成相应的吩嗪,但优选在5,10-位的一个或两个上衍生化,以形成单取代或二取代的二氢吩嗪或双(二氢吩嗪)。 最优选地,在一锅合成中从儿茶酚和1,2-二氨基芳基化合物开始制备5,10-二烷基-5,10-二氢吩嗪。 该产品可用作染料,特别是作为电致变色系统中的发色团。
