The efficient catalytic systems for the synthesis of cyclic carbonates generally consist of two components such as metal-based Lewis acid for epoxide coordination and ammonium halide as a nucleophile for the ring opening. Although one-component catalytic systems for the synthesis of cyclic carbonates are seldom known in the literature, the typical one-component catalysts reported in the literature are known to have the form of ammonium halides tethered to the chelating ligands coordinated to the metal center.¹ To the best of our knowledge, there have been no reported studies on one-component and neutral catalytic systems containing no tethering salts in a molecule. Recently, we reported tertiary amines as a new class of highly efficient organocatalysts for the synthesis of cyclic carbonates.² In addition, many chromium-based compounds are known to be very active catalysts for the coupling reaction of CO₂ and epoxides³ however, no examples of their congeners such as molybdenum- and tungsten-based compounds as catalysts for the coupling reaction of CO₂ and epoxides are reported in the literature. In this poster session, we will report the synthesis of new Cr-, Mo-, and W-based compounds containing bidentate tertiary amines and their application as catalysts in the absence of any additives for the synthesis of cyclic carbonate.
