for formyl‐selective deuterium labeling of aromatic aldehydes under mild conditions, using an iridium‐based catalyst designed to favor formyl over aromatic C−H activation. A good range of aromatic aldehydes is selectively labeled, and a one‐pot labeling/olefination method is also described. Computational studies support kinetic product control over competing aromatic labeling and decarbonylation pathways
我们报告了第一种直接催化方法,该方法在温和条件下使用了基于铱的催化剂,旨在优先于甲酰胺而不是芳香族CH活化,从而在芳香族条件下对芳香族醛进行甲酰选择性氘标记。有选择地标记了各种芳香醛,并描述了一种单锅标记/烯烃化方法。计算研究支持动力学产品控制竞争性的芳香族标记和脱羰途径。
