制备方法与用途

合成方法

4-氧代-2-四氢吡喃酸（10克）溶于150毫升冰醋酸中，加入装有2克5% Pd/C的高压釜中，通入氢气，在0.4兆帕压力和75℃下反应，直至体系不再吸氢为止。通过薄层色谱（TLC）检测原料点消失后，冷却、过滤并旋蒸除去溶剂，得到黑色固体。然后用乙醚溶解该固体，并依次用水合碳酸钠萃取三次（每次150毫升），再用乙醚洗涤三次（每次150毫升）。酸化后进行过滤，最终获得白色固体。通过甲苯重结晶可得白色晶体2-四氢吡喃酸8.2克。

  Visible‐light‐induced heterogeneous photocatalysis for decarboxylative alkynylation has been performed. The using of cheap, metal‐free and recyclable graphitic carbon nitride (g‐C3N4) as the photoredox catalyst in the process enables the facile transformation of a variety of carboxylic acids into structurally diverse alkyne‐containing molecular architectures under mild and environmentally‐benign conditions

  可见光诱导的非均相光催化脱羧炔基反应。使用便宜，无金属且可回收的石墨氮化碳（g ‐ C 3 N 4）作为该过程中的光氧化还原催化剂，可以在温和和环境友好的条件下将多种羧酸轻松转化为结构多样的含炔分子结构。明显地，反应系统的非均质性质允许催化剂在多次运行中的回收和再利用而不损失反应性。光催化反应也可以以连续流动的方式进行并按比例放大至克级。此外，该策略在未活化烯烃的1，2氨基炔基化中的应用进一步凸显了该策略的制备能力。
