A new tandem catalytic process was designed and developed as a tool for the direct conversion of the widely available feedstock 2,7‐octadienol into an α,ω‐diester. This innovative auto‐tandem catalysis is atom efficient and consists of three consecutive palladium‐catalysed reactions: ether formation, ether carbonylation and alkoxycarbonylation. By using the design of experiments (DoE) approach, significant
设计并开发了一种新的串联催化工艺,将其作为将广泛使用的原料2,7-辛二烯醇直接转化为α,ω-二酯的工具。这种创新的自动串联催化是原子有效的,由三个连续的钯催化反应组成:醚形成,醚羰基化和烷氧羰基化。通过使用实验设计(DoE)方法,确定了重要的参数,并优化了所需的α,ω-二酯的收率。模型底物使人们可以更深入地了解反应的进程,因此,发现了反应顺序。此外,通过简单地应用其他配体,可以遵循不同的反应路径,从而可以探索其他新的串联催化序列,并能够获得新的化合物。
