Gases, being lightweight and arguably the most atom-efficient choice of reagents for various transformations, present a unique set of challenges when it comes to their practical use in the laboratory environment. The inherent difficulties in handling gases using conventional batch equipment, coupled with the physical separation of gases and liquid reaction mixtures due to gravity, often discourage their utilization. When gases serve as reagents, they need to diffuse within the reaction mixture before they can react effectively. To overcome this limitation, researchers frequently turn to Henry's law, which allows for the enhancement of gas solubility by increasing the pressure within the vessel. However, this approach necessitates specialized equipment, such as Parr bombs, and additional safety precautions. As a consequence, setting up multiple reactions concurrently becomes impractical, resulting in a slow pace of reaction discovery and optimization. To circumvent these challenges, chemists often resort to the development of engineered reagents that are crystalline, easy to handle and store. However, such reagents tend to be more expensive and less atom-efficient than their gaseous counterparts.
