开发了一种从肼衍生物合成偶氮化合物的简便方法。这代表了 Selectfluor 介导的肼衍生物氧化脱氢的史无前例的例子。该反应可能通过 N-氟化和消除过程进行。该协议具有操作简单、条件温和、官能团耐受性好、效率高等特点。此外,磺酰基取代的偶氮化合物在 4 W 蓝色 LED 照射下以优异的产率转化为乙酰苯胺也突出了该优势。
An efficient palladium-catalyzedSuzukicross-coupling reaction of N′-mesyl arylhydrazine with aryl boronic acid is described, which affords the corresponding biaryl compounds in high yields. This transformation proceeds through C–N bond cleavage under mild conditions.
