An improved procedure for the aminocarbonylation of benzyl chloride derivatives using carbon monoxide and either primary or secondary amines has been developed. Studying the competing background alkylation reaction allowed the solvent and base to be selected for a simple catalyst screen, which, in turn, enabled the discovery of a method for the preparation of 2-arylacetamides under mild conditions, with minimal side-products using an inexpensive phosphine ligand. This non-traditional optimisation strategy allowed us to overcome the background alkylation, which has been cited as justification for the development of more complex and less atom-economical approaches.

氯化苄的高效钯催化氨基羰基化

已经开发了一种使用一氧化碳和伯胺或仲胺对苄基氯衍生物进行氨基羰基化的改进方法。研究竞争背景烷基化反应可以选择溶剂和碱进行简单的催化剂筛选，这反过来又使发现了一种在温和条件下制备 2-芳基乙酰胺的方法，使用廉价的副产物膦配体。这种非传统的优化策略使我们能够克服背景烷基化，这被认为是开发更复杂和原子经济性更低的方法的理由。
