Hydrogen atom transfer‐mediated intramolecular C−C coupling reactions between alkenes and nitriles, using PhSiH3 and catalytic Fe(acac)3, are described. This introduces a new strategic bond disconnection for ring‐closing reactions, forming ketones via imine intermediates. Of note is the scope of the reaction, including formation of sterically hindered ketones, spirocycles and fused cyclic systems.
描述了使用PhSiH 3和催化Fe(acac)3的氢原子转移介导的烯烃与腈之间的分子内C-C偶联反应。这为闭环反应引入了新的战略性键断开连接,可通过亚胺中间体形成酮。值得注意的是反应的范围,包括空间位阻的酮,螺环和稠合的环状体系的形成。
