Here, we describe that simple ketones can be efficiently employed as electrophiles in Suzuki-Miyaura coupling reactions via catalytic activation of unstrained C-C bonds. A range of common ketones, such as cyclopentanones, acetophenones, acetone and 1-indanones, could be directly coupled with various arylboronates in high site-selectivity, which offers a distinct entry to more functionalized aromatic ketones. Preliminary mechanistic study suggests that the ketone α-C-C bond was cleaved via oxidative addition.

通过活化无应变碳-碳键进行简单酮的铃木-宫浦偶联

在这里，我们描述了通过催化激活无张力的 CC 键，简单的酮可以在 Suzuki-Miyaura 偶联反应中有效地用作亲电子试剂。一系列常见的酮，如环戊酮、苯乙酮、丙酮和1-茚满酮，可以直接与各种芳基硼酸酯以高位点选择性偶联，这为获得更多功能化的芳香酮提供了独特的途径。初步机理研究表明酮 α-CC 键通过氧化加成断裂。
