  无过渡金属的分子内碳原子芳族取代/Büchner反应：芴和[6,5,7]苯并稠合环的合成

  摘要：

  分子内芳族取代和Büchner反应已被认为是构建多环化合物的有力方法。传统上，这些反应是由Rh II催化剂以α-重氮羰基化合物为底物催化的。本文介绍了无过渡金属的分子内芳族取代/Büchner反应。这些反应使用现成的N-甲苯磺酰hydr作为重氮化合物的前体，并显示出较宽的底物范围。

  New Fluorogenic Probes for Oxygen and Carbene Transfer:  A Sensitive Assay for Single Bead-Supported Catalysts

  摘要：

  A high-throughput screening assay for atom transfer catalysis has been developed. This assay is based on two probes, developed herein, which generate highly fluorescent products upon carbene or oxygen atom transfer. The emission wavelength of probes 1 and 5 shift significantly (up to 90 nm) upon epoxidation, allowing detection of product at 3% conversion. Probe 7 is not fluorescent, while fluorescence emission by carbene insertion/rearrangement product 8 allows detection at less than 1% conversion. Such sensitivity allows for examination of single-bead reactions in a high throughput array format (1536 wells per plate), and provides a broad detection window ranging from single to high turnover numbers. Thousands of metal complexes are evaluated in a single screening experiment. Preliminary screening of a diverse ligand library with probe 7 in the presence of Rh(II) uncovered new catalysts capable of cyclopropanation and C-H insertion.

  iminyl‐radical formation has been established for the construction of pyridines, quinolines, and phenanthridines from acyl oximes. With fac‐[Ir(ppy)3] as a photoredox catalyst, the acyl oximes were converted by 1 e− reduction into iminyl radical intermediates, which then underwent intramolecular homolytic aromatic substitution (HAS) to give the N‐containing arenes. These reactions proceeded with a broad
