As a part of our programme directed towards the synthesis of some fused pyridazine derivatives, we reported recently a novel method for the synthesis of some 4-aroyl-6-phenylpyridazin-3(2H)-ones and 4-aroyl-3-chloro-6-phenylpyridazines as readily available starting materials for this purpose. In the present investigation the reaction of 4-aroyl-3-chloro-6-phenylpyridazines (Ia-Ic) with some nucleophiles is studied.
作为我们专注于合成一些融合吡啶嗪衍生物的计划的一部分,我们最近报道了一种新颖的合成方法,用于合成一些4-酰基-6-苯基吡啶嗪-3(2H)-酮和4-酰基-3-氯-6-苯基吡啶嗪作为可获得的起始物料。在本研究中,研究了4-酰基-3-氯-6-苯基吡啶嗪(Ia-Ic)与一些亲核试剂的反应。
