Synthesis of Linear and Cyclic Carbonates

Bond Activation and Catalysis by Ruthenium Pincer Complexes

“…Efficient hydrogenation of CO 2 into methanol under mild conditions remains highly desirable. Dimethyl carbonate is produced by direct reaction of CO 2 with 2 equiv of methanol in the presence of dehydrating agents, or from oxidative carbonylation of methanol …”

Proline-Catalysed Amination Reactions in Cyclic Carbonate Solvents

“…Cyclic carbonates are prepared by the 100% atom economical reaction between carbon dioxide and ethylene or propylene oxide ( Scheme 1 ) [ 31 , 32 , 33 , 34 , 35 ]. We have shown that, in the presence of an appropriate catalyst, the synthesis of cyclic carbonates 2 and 3 can be achieved at atmospheric pressure and room temperature for batch processes [ 36 , 37 , 38 , 39 ] and at temperatures of 100 °C or below in a gas phase flow reactor [ 40 , 41 ].…”

Umwandlung von Kohlendioxid mit Übergangsmetall‐Homogenkatalysatoren: eine molekulare Lösung für ein globales Problem?

“…[172,177] Bis jetzt gibt es zwei Routen, um cyclische Carbonate aus Kohlendioxid über homogene Übergangsmetallkatalyse zu erhalten: mit (Propargyl-)Alkoholen oder mit Epoxiden (Oxiranen). [179,180] sowie zweikernige Salenkatalysatoren.…”
