Towards a sustainable electrochemical activation for recycling CO2: synthesis of bis-O-alkylcarbamates from aliphatic and benzyl diamines

Abstract

Carboxylation of aliphatic and benzyl diamines with electrochemically activated CO₂ led to the synthesis of bis-O-alkyl carbamates in high yields. Reaction conditions, including the geometry of the electrochemical cell, were discussed and optimized. This resulted in a significant reduction of unwanted material associated with the reaction, overcoming the economic and environmental restrictions to its application on large scale.
