NaCl significantly enhanced the longer oligoarginine formation in the oligomerization of L ‐arginine activated by N,N ′‐carbonyldiimidazole (CDI) in homogeneous aqueous solution. The optimal concentration of NaCl for the highest yield of longer oligoarginine formation is around 1 M . It is suggested that the weak interactions of Cl − with the positive‐charged guanidinium group of the oligoarginines formed in the oligomerization of L ‐arginine are responsible for the enhancement by NaCl. © 2005 Wiley Periodicals, Inc.
