2-Imidazolines were synthesized via CuCN-TsOH catalyzed cyclization of nitriles with ethylenediamine in a continuous-flow microreactor. The CuCN-TsOH dissolves in ethylenediamine homogeneously and is a suitable catalyst for the continuous reactions. Under the flow condition, the 2-imidazolines were obtained with high yields in 5 min for most substrates. The "in-tube retention time gradient" (IT-RTG) is achieved in the continuous-flow microreactor, and it is applied in monitoring the reaction progress.

Key words: continuous-flow microreactor, 2-imidazoline, catalysis, cuprous cyanide, nitrile, cyclization
