报道了一类新的环状（烷基）（氨基）卡宾，我们称之为环状（氨基）（桶烯）卡宾（CABC）。关键的合成步骤包括蒽衍生物与炔的分子内[4+2]环化。这种合成方法允许芳基和烷基基团连接在氮原子上。当用作配体时，两个桶烯氢与金属紧密接触，这可以稳定低价催化中间体。
A novel family of cyclic (alkyl)(amino)carbenes, which we name cyclic (amino)(barrelene)carbenes (CABCs) is reported. The key synthetic step involves an intramolecular [4+2] cyclization of an anthracene derivative with an alkyne. This synthetic approach allows for the attachment of both aryl and alkyl groups on the nitrogen atom. When used as ligand, two of the barrelene hydrogens are in close contact with the metal, which could stabilize low valent catalytic intermediates.
