5‐tetrazines in bioorthogonal chemistry and functional materials. Lewis acid metal catalysts—most notably divalent nickel and zinc salts—are described to catalyze the one‐pot synthesis of 1,2,4,5‐tetrazines directly from aliphatic nitriles (see scheme).
铺路:缺乏方便的合成方法是 1,2,4,5-四嗪在生物正交化学和功能材料中更广泛使用的重大障碍。路易斯酸金属催化剂——最显着的是二价镍和锌盐——被描述为直接从脂肪腈催化一锅法合成 1,2,4,5-四嗪(见方案)。
