In contemporary synthetic laboratories, the utilization of toxic and hazardous gaseous compounds is subject to stringent regulations and control measures. The elusive nature of gases makes handling and dosing of these reagents a formidable challenge when employing traditional batch equipment. This has prompted the scientific community to devise engineered chemicals that can release in situ the desired gases via a chemical reaction. Alternatively, some solid reagents have been developed to serve as gas surrogates to perform the same types of transformations. However, these approaches often suffer from inefficiency due to the formation of stoichiometric by-products, and, paradoxically, they frequently necessitate the initial use of the parent gases for the synthesis of the reagents.
