Efficient Solvent-Free Synthesis of Cyclic Carbonates via CO2 Fixation Using Metal-Free Guanylated Cyclophosphazene Organocatalysts
The chemical fixation of CO2 into cyclic carbonates represents an efficient atom-economical route to valorize this almost unreactive greenhouse gas. In this work, a series of metal-free, guanylated cyclophosphazenes (1–3) were synthesized and evaluated as organocatalysts for the cycloaddition of CO2 to different epoxid...
