development of new strategies to synthesize alkyl arenes is a highly desirable goal, and herein, we present an alternative method to those conventional reactions. Particularly, a simple protocol for the direct C−H alkylation of unbiased arenes with alkylboronic acids in the presence of Mn(OAc)3⋅2H2O is reported. Primary or secondary unactivated alkylboronic acids served as alkylating agents for the direct
芳烃的烷基化是重要的合成步骤,不仅从学术角度来看,而且在大宗化学工业中也是如此。尽管有其局限性,但Friedel-Crafts反应仍然是大多数芳烃烷基化过程的首选方法。因此,开发合成烷基芳烃的新策略是非常需要的目标,在此,我们提出了那些常规反应的替代方法。特别地,一个简单的协议用于在Mn的存在下与烷基硼酸偏芳烃的直接C-H的烷基化(OAC)3 ⋅2H 2报告为O。伯或仲未活化的烷基硼酸用作烷基化剂,用于代表性的多芳烃(PAHs)或苯的直接官能化。结果与自由基机制一致。
