Abstract

The regioselectivity of copper(I)-catalyzed synthesis of 1,2,3-triazoles in dabco-based ionic liquids has been investigated at the DFT level using a supermolecular approach. The analysis of the theoretical results shows that the coordination ability of the ionic liquid (IL) anion to copper(I) catalyst and to all the other species containing the copper (intermediates and transition states) can significantly affect product distribution. Possible catalyst sequestering effects and the ability to stabilize selectively new intermediate species have been envisaged, as probable mechanisms throughout IL anions can affect copper catalyzed reactions inside performed.
