Multiphasic Continuous‐Flow Reactors for Handling Gaseous Reagents in Organic Synthesis: Enhancing Efficiency and Safety in Chemical Processes

Abstract

AbstractThe use of reactive gaseous reagents for the production of active pharmaceutical ingredients (APIs) remains a scientific challenge due to safety and efficiency limitations. The implementation of continuous‐flow reactors has resulted in rapid development of gas‐handling technology because of several advantages such as increased interfacial area, improved mass‐ and heat transfer, and seamless scale‐up. This technology enables shorter and more atom‐economic synthesis routes for the production of pharmaceutical compounds. Herein, we provide an overview of literature from 2016 onwards in the development of gas‐handling continuous‐flow technology as well as the use of gases in functionalization of APIs.
