Abstract
We report the cerium photocatalyzed radical decarboxylative hydrazination of carboxylic acids with di-tert-butylazodicarboxylate (DBAD). The operationally simple protocol provides rapid access to synthetically useful hydrazine derivatives and overcomes current scope limitations in the photoredox-catalyzed decarboxylation of carboxylic acids.
摘要
我们报告了铈光催化的羧酸与二-tert-丁基偶氮二羧酸酯（DBAD）的自由基脱羧肼化反应。该操作简单的方案为合成有用的肼衍生物提供了快速途径，并克服了目前光氧化还原催化羧酸脱羧反应的范围限制。
