Abstract:
The growing emphasis on sustainable chemistry has driven research into utilizing carbon dioxide (CO2) as a nontoxic, abundant, and cost-effective C1 building block. CO2 offers a promising avenue for direct conversion into valuable chemicals ranging from fuels to pharmaceuticals. This review focuses on the utilization of CO2 for reductive N-formylation/N-methylation reactions of various amines, providing advantages over conventional methods involving toxic CO and other methylating reagents. The approach employs readily available reductants such as silane, borane reagents, and hydrogen (H2). The discussion encompasses recent developments in transition metal and organocatalyst systems for these reactions, highlighting mechanistic interpretations and factors influencing product selectivity.
摘要:
对可持续化学的日益重视推动了利用二氧化碳(CO2)作为无毒物质的研究,丰富,和具有成本效益的C1积木。二氧化碳为直接转化为从燃料到药品等有价值的化学品提供了一个有希望的途径。这篇综述的重点是利用CO2进行各种胺的还原N-甲酰化/N-甲基化反应,提供优于涉及有毒CO和其他甲基化试剂的常规方法的优点。该方法采用容易获得的还原剂,如硅烷,硼烷试剂,氢气(H2)讨论包括这些反应的过渡金属和有机催化剂体系的最新进展,突出机理解释和影响产品选择性的因素。
