Bifunctional Porphyrin Catalysts for the Synthesis of Cyclic Carbonates from Epoxides and CO: Structural Optimization and Mechanistic Study.

We prepared bifunctional Mg porphyrin catalysts 1 for the solvent-free synthesis of cyclic carbonates from epoxides and CO. The activities of Id, lh, and li, which have Br , Cl, and I counteranions, respectively, increased in the order li < lh < Id. Catalysts Id and l j—m, which bear four tetraalkyl...
