Developing clean synthetic methodology for the production of carbamates, avoiding phosgene, is a very attractive perspective.In this paper, the reactivity of industrially relevant amines, aliphatic and aromatic, towards CO2 and alkylating agents, or dialkyl/aryl-carbonates, is discussed. We also describe the catalytic role of carbon dioxide in the carbamation of aliphatic amines and that of P-acids in the reaction of aromatic amines towards carbonates. The reaction mechanism is discussed.

Abstract
Developing clean synthetic methodology for the production of carbamates, avoiding phosgene, is a very attractive perspective.In this paper, the reactivity of industrially relevant amines, aliphatic and aromatic, towards CO2 and alkylating agents, or dialkyl/aryl-carbonates, is discussed. We also describe the catalytic role of carbon dioxide in the carbamation of aliphatic amines and that of P-acids in the reaction of aromatic amines towards carbonates. The reaction mechanism is discussed.File in questo prodotto:
