To find a useful, practical, and ecologically safer way to synthesize protected amines, the reactions of amines with benzyl halides under CO 2 atmosphere were systematically examined. For primary amines, the CO 2 -inserted products were obtained in higher yields in the presence of DBU as a base, under a high pressure of CO 2 , and in a low-polarity solvent (toluene/hexane 1 : 1). Secondary amines gave only low yields of CO 2 -inserted products.
