Conversion of Oxiranes and CO2 to Organic Cyclic Carbonates Using a Recyclable, Bifunctional Polystyrene‐Supported Organocatalyst.

Organocatalysts based on polystyrene-supported pyrogallol are synthesized starting from azidomethyl polystyrene and used for title conversion to prepare cyclic carbonates [(III), (V), (VII), and (VIII)].
