  the first amide cross-coupling by direct metal insertion of simple and readily available primary amides. The overall strategy by N,N-di-Boc activation/metal insertion is suitable for a broad range of coupling protocols via acylmetals. Mechanistic experiments suggest high reactivity of N,N-di-Boc activated 1° amides in direct amide C–N cross-couplings.

  作者：Harvey J. A. Dale、Chris Nottingham、Carl Poree、Guy C. Lloyd-Jones

  DOI：10.1021/jacs.0c12400

  日期：2021.2.3

  carbenes undergo rapid inter- and intramolecular reactions and rearrangements, including 1,2-migrations of β-substituents to generate alkynes. Their propensity for substituent migration exerts profound influence over the broader utility of alkylidene carbene intermediates, yet prior efforts to categorize 1,2-migratory aptitude in these elusive species have been hampered by disparate modes of carbene generation

  亚烷基卡宾经历快速的分子间和分子内反应和重排，包括 β-取代基的 1,2-迁移以生成炔烃。它们取代基迁移的倾向对亚烷基卡宾中间体的更广泛用途产生了深远的影响，但之前在这些难以捉摸的物种中对 1,2-迁移能力进行分类的努力受到了不同的卡宾生成模式、超短卡宾寿命、机械歧义和需要单独制备一系列 13C 标记的前体。在此，我们报告了通过羰基化合物与 [13C]-Li-TMS-重氮甲烷的同系化原位生成的 13C-亚烷基卡宾的重排，这种方法不需要同位素标记的底物并加快了系统研究（13C 1H}核磁共振，DLPNO-CCSD(T)) 在前所未有的超过 30 亚烷基卡宾范围内的迁移能力。对 26 种差异取代的二苯甲酮反应的哈米特分析揭示了亚烷基卡宾中 1,2-迁移的几个违反直觉的特征，这些特征可能在更普遍的不饱和卡宾的研究和合成应用中被证明是有用的。

  作者：Stefano Parisotto、Lorenzo Palagi、Cristina Prandi、Annamaria Deagostino

  DOI：10.1002/chem.201800765

  Palladium(0)‐catalysed hydro‐alkylation or ‐alkenylation of alkoxyallenes with N‐tosylhydrazones gives direct access to conjugated and skipped 1‐alkoxydienes with high efficiency and excellent functional‐group compatibility. The reaction is proposed to involve the in situ‐formed t‐butanol as proton source in the key step of the allylpalladium(II) species generation. Moreover, lithium iodide or iodobenzene
