New sustainable approaches should be developed to overcome equilibrium limitation of dialkyl carbonate synthesis from CO2 and alcohols. Using tetraethyl orthosilicate (TEOS) and CO2 with Zr catalysts, we report the first example of sustainable catalytic synthesis of diethyl carbonate (DEC). The disiloxane byproduct can be reverted to TEOS. Under the same conditions, DEC can be synthesized using a wide

A series of organo(alkoxy)disiloxanes was obtained by the reaction of carbondioxide with sodium alkoxy(organo)silanolates under high pressure as well as by bubbling CO2 through the reaction mixture. It has been suggested that the reaction involves the intermediate formation of carbonate derivatives of sodium alkoxy(organo)silanolates.
