acyl-based carbanion equivalents. We herein report an alternative strategy that is based on the use of aldehydes as alkyl carbanion equivalents in a reductive coupling with aryl imines. A wide array of secondary amines can be synthesized in moderate to high yields. This reaction is mediated by hydrazine and catalyzed by ruthenium(II) complexes, and it tolerates various functional groups, such as esters, amides
Transition-metal free: The synthesis of imines from benzyl alcohol and anilines promoted by oxygen and KOtBu at room temperature in the absence of a transition metal catalyst is described. The detailed investigation of the radical mechanism is presented revealing complex reaction paths and branching patterns.
无过渡金属:描述了在室温下,在没有过渡金属催化剂的情况下,在氧气和 KO t Bu 的促进下,由苯甲醇和苯胺合成亚胺。对自由基机理的详细研究揭示了复杂的反应路径和分支模式。
