  联苯-2-羧基的分子内环化：II-状态芳酰氧基的证据

  摘要：

  酰基次碘酸盐均相裂解产生的联苯-2-羧基自由基分子内环化，主要通过Ar 2 -6环化生成δ-内酯。2'-烷氧基联-2-羧基不产生预期的Ar 1个-5环化产物，但经历均裂本位的2'-取代的3'-取代。菲-4-羧基产生5 H-菲[4,5- bcd] pyran-5-one。考虑到所涉及的分子轨道表明，联苯-2-羧基处于π基态且具有较高的能量，因此比相应的酰胺基自由基具有更小的热可及性Σ态。建议容易脱羧的酰氧基具有∑基态或热可接近的激发∑态。

  Photocatalytic Dehydrogenative Lactonization of 2-Arylbenzoic Acids

  摘要：

  A metal-free dehydrogenative lactonization of 2-arylbenzoic acids at room temperature was developed. This work illustrates the first application of visible-light photoredox catalysis in the preparation of benzo-3,4-coumarins, an important structural motif in bioactive molecules. The combination of photocatalyst [Acr(+)-Mes] with (NH4)(2)S2O8 as a terminal oxidant provides an economical and environmentally benign entry to different substituted benzocoumarins. Preliminary mechanistic studies suggest that this reaction most likely occurs through a homolytic aromatic substitution pathway.

  Aryl carboxylic acids are among the most abundant substrates in chemical synthesis and represent a perfect example of a traceless directing group that is central to many processes in the preparation of pharmaceuticals, natural products and polymers. Herein, we describe a highly selective method for the direct step-down reduction of carboxylic acids to arenes, proceeding via well-defined Pd(0)/(II)
