 After several more hours of sitting at room temperature under vacuum, total release of CO2 and FLP regeneration had occurred.The intramolecular FLP-CO2 compound by contrast was stable as a solid at room temperature but fully decomposed at temperatures above -20 °C as a solution in dichloromethane releasing CO2 and regenerating the FLP molecule.This method of FLP carbon capture can be adapted to work in flow chemistry systems.
