P-Campus-Ringvorlesung am 16.12.21

Am 16. Dezember findet der nächste Vortrag der P-Campus-Ringvorlesung 2021 statt. Constanza Terazzi vom Leibniz-Institut für Katalyse (LIKAT) referiert zum Thema "Development of P-based Organocatalysts for CO2 Fixation into Cyclic Carbonates". Der Vortrag wird auf Englisch gehalten und beginnt um 15:00 Uhr.

Zur Anmeldung

Increasing levels of CO2 emissions have motivated the valorization of this greenhouse gas as a C1 building block. However, chemical fixation of CO2 into valuable products remains as a challenge due to its thermodynamic and kinetic inertness. In this regard, an interesting and useful reaction is the synthesis of cyclic carbonates by non-reductive addition of CO2 to epoxides.[1] Among reported catalysts, phosphonium salts offer great advantages due to their high activity, stability and potential recyclability.[2] Furthermore, their versatility allows modifications on their structure that led to the rational design of highly efficient bifunctional catalysts.[3a-c] Herein the development of phosphonium salts for CO2 fixation into cyclic carbonates will be presented in detail, together with perspectives for future research on the topic.
