The reaction of pyridin-2(1H)-ones with PhICl2 and NH4SCN enables an efficient regioselective thiocyanation, leading to the synthesis of the biologically interesting C5 thiocyanated 2-pyridones in good to high yields. The mechanistic pathway of this metal-free approach is postulated to involve the formation of the reactive thiocyanogen chloride from the reaction of PhICl2 and NH4SCN followed with the
吡啶-2(1 H )-酮与PhICl 2和NH 4 SCN 的反应可实现有效的区域选择性硫氰化,从而以良好或高产率合成具有生物学意义的C5 硫氰化2-吡啶酮。这种无金属方法的机械途径被假定为涉及从 PhICl 2和 NH 4 SCN的反应形成反应性氯化硫氰,然后是吡啶-2(1 H )-一个环的区域选择性亲电硫氰化。
