Sažetak
Click chemistry, an approach to synthesis using fast, versatile and high yielding reactions, has recently attracted attention as a simple way of preparing a wide scope of products. 1, 2, 3‐ triazoles can be prepared by Huisgen 1, 3‐ cycloaddition of azides and alkynes, where copper (I) as the catalyst dictates the formation of a 1, 4‐disubstituted triazole ring [1]. The triazole group is a weak base and depending on the conditions it can act both as a donor or acceptor of protons, as well as a ligand for coordinating metals [2]. The large dipole moment of triazole molecules (5 D) allows easy formation of hydrogen bonds, as well as dipole‐dipole and π interactions, which increase their solubility and allow binding to biological targets [3]. In this work, bis‐ and mono‐1, 2, 3‐triazole ligands and their metal complexes were prepared. Complexes of the thiazole ligand 4c were fully characterized by NMR, UV/Vis and IR spectroscopy. (SMD)/M05‐2X/6‐31+G(d)/LanL2DZ + ECP calculations helped in interpreting relative stabilities of mer, trans‐fac and cis‐ fac isomers of ML2 complexes. The prepared ligands and complex 4cZn will be tested for their antiproliferative properties.
