Two copper(II) complexes with benzotriazole‐based ligands having pyridyl and quinolinyl arms were synthesized in good yields and characterized fully via spectroscopic and crystallographic techniques. The crystalstructures of the complexes revealed different coordination environments around copper(II) centers. The difference in structure was due to the steric effect of the ligands, which resulted in

multicomponent reaction of benzyl halides with sodium azide and terminal alkynes. This catalyst allowed for the high regioselectivesynthesis of 1,4-disubstituted 1,2,3-triazoles through a one-step and atom economic tandem reaction with water as the solvent. Note that no additional base or ligand or reducing agent is required. Moreover, in addition to benzyl halides, hetero benzyl halides have also been
