The title azine(I) can be conveniently prepared by treatment of 1,2-bistrifluoroacetylhydrazine with - dimethylaniline hydrochloride in phosphoryl chloride at . 100 °C. It undergoes facile displacement of one or both chlorine atoms on treatment with a variety of nitrogen-, oxygen- and sulphur-centred nucleophiles as well as with iodide and fluoride ions. The bisanilino-substituted azine (Vd) is thermally
可以通过在氯化磷酰氯中用-二甲基苯胺盐酸盐处理1,2-双三氟乙酰肼来方便地制备标题嗪(I)。100℃。在用各种以氮,氧和硫为中心的亲核试剂以及碘离子和氟离子处理后,它容易发生一个或两个氯原子的置换。双氨基壬基取代的嗪(Vd)具有热稳定性,并且环化反应中苯胺被消除成三唑(Vla),而全氟嗪(Vj)与乙炔进行环加成反应。
