  摘要：

  详细介绍了高活性和选择性的基于卟啉的环氧化物羰基化催化剂 [(OEP)Cr(THF)2][Co(CO)4]（1；OEP = 八乙基卟啉；THF = 四氢呋喃）的开发。配合物 1 是一个分离的离子对，由四羰基钴酸根阴离子和八面体铬卟啉配合物通过两个 THF 配体轴向连接而成。关于环氧化物羰基化为 β-内酯，催化剂 1 表现出优异的周转数（高达 10,000）和周转频率（高达 1670 h(-1)），在氧和空间位阻较小的碳之间发生区域选择性羰基插入环氧底物。配合物 1 对非质子官能团具有高度耐受性，可将一系列脂肪族和脂环族环氧化物以及带有侧链醚、酯和酰胺的环氧化物羰基化。通过对缩水甘油酯羰基化反应条件的仔细控制，实现了β-或γ-内酯异构体的独家生产。通过反应立体化学分析，提出了γ-内酯产物的形成机制。总体而言，已经通过使用 [(OEP)Cr(THF)2][Co(CO)4] 的催化羰基化以快速和

  Reactor systems and processes produce organic acids through thermolysis of polylactones. The reactor systems and processes introduce at least one epoxide reagent and carbon monoxide reagent to at least one reaction vessel through at least one feed stream inlet.
