Using n-butylamine as a template, the laws of palladium-catalyzed carbonylation of primary amines in supercritical carbon dioxide media and conventional organic solvents were compared. The results show that the chemical selectivity of palladium-catalyzed carbonylation of primary amines in supercritical carbon dioxide has changed, and that the cosolvent also has a large effect on the chemical selectivity and yield of the reaction
