Oximinoalkylamines were found to be efficient ligands for acceleration of the CuAAC reaction. 'Mixed' oxime-triazole ligands TzβOx2 and Tz2 βOx demonstrate an approximately 10-fold enhanced acceleration effect compared to commonly employed ligand TBTA using 0.1 mol % of the [Cu]/L catalytic system. The optimal catalytic system based on readily available TzβOx2 provided 1,4-disubstituted triazoles in high yields with short reaction times. © 2015 Elsevier Ltd.
