  摘要：

  在1.25当量的亚硫酰氯存在下，将羧酸在DMF中于150℃加热，以良好的产率得到相应的N，N-二甲基酰胺。一锅法发生串联氯化和酰胺化反应。二羧酸需要延长反应时间才能以高收率生产双酰胺。在4,4'-二酯存在的情况下，在酰氯缩合条件下，一些苯甲酰胺被有效地转化为相应的1,2-二芳基-1,2-二酮（苯）。丁基丁基联苯（DBB）在THF中的溶液。超声波辐照有效地加速了反应，但这不是关键。然而，DBB的存在对反应是致命的。尽管到目前为止，已经报道了几种由苯甲酸合成苯甲醚的方法，但该方法是最方便，可重复性最高的方法之一。

  Catalytic Lactonization of Unactivated Aryl C–H Bonds with CO₂: Experimental and Computational Investigation

  摘要：

  The first catalytic lactonization of unactivated aryl C-H bonds with CO2 to afford important phthalides is reported. Notably, this method features high selectivity, excellent functional group tolerance, smooth scalability, and facile product diversification. DFT calculations reveal that a novel insertion of two CO2 into the O-Pd bond of a palladacycle might be the key step, providing great potential and a different perspective for carbonylation with CO2.
