At 130Β°C and in the presence of compressed CO 2 , primary aliphatic amines [RNH 2 , R=C 10 H 21 , C 8 H 17 , cHex, 1-(C 10 H 7 )CH 2 ] react with organic carbonates (R%OCO 2 R%; R%=Me, Et) to give alkyl carbamates (RNHCO 2 R%, 1). Although CO 2 promotes the reaction also at a low pressure, good yiel
