Application
- Efficient catalysis of CO2 cycloaddition: 1,2-Epoxybutane is utilized in the synthesis of hydroxy-rich covalent organic frameworks, proving effective in catalyzing CO2 cycloaddition. This application supports environmental sustainability efforts through the conversion of carbon dioxide into useful compounds (Pang et al., 2023).
- Strain-release reagent synthesis: Highlighting its versatility as a chemical intermediate, 1,2-Epoxybutane is used in one-pot syntheses of strain-release reagents from methyl sulfones. This research opens new avenues in synthetic chemistry for creating novel organic compounds efficiently (Jung and Lindsay, 2022).
