“…2. In a recent paper [10], our research group already digged the CCDC [26] database for the few Pd complexes having the C 3 N 2 donor set; the complex described here is (to the best of our knowledge) the second reported example of a mononuclear h 3 -allyl Pd complex showing a C 3 N 2 donor set hosting a pyridyl-triazole ligand. In the following discussion we will make a detailed comparison of the two structures.…”

In recent years, metal complexes of organo 1,2,3-triazole click-derived ligands have attracted significant attention as catalysts in many chemical transformations and also as biological and pharmaceutical active agents. Regarding the important applications of these metal-organo 1,2,3-triazole-based complexes, in this review, we focused on the recently reported investigations of the structural, electronic, and spectroscopic aspects of the complexation process in transition metal complexes of 1,2,3-triazole-based click ligands. In line with this, the coordination properties of these triazole-based click ligands with transition metals were studied via several quantum chemistry calculations. Moreover, considering the complexation process, we have presented comparative discussions between the computational results and the available experimental data.

“…In fact, in the 1 H NMR spectrum (CD 3 OD, 298 K) of 2 both the H(1) doublet and the H(7) singlet are found significantly downfield with respect to the free ligand ( ı = 0.57 and 0.33 ppm, respectively) as found for other pyridyl-triazole ligands when chelating to a metal centre [23,31,32]. Definitive evidence for chelation of 1 at ruthenium comes from the AB spin pattern found for the methylene bridge protons.…”

a b s t r a c tThe water soluble pyridyl-triazole ligand sodium 2-(1-((pyridin-2-yl)methyl)-1H-1,2,3-triazol-4-yl) ethyl sulfate (Na1) has been successfully employed in combination with ruthenium and iridium for catalytic hydrogenation of C C and C O double bonds in water/toluene biphasic systems. Reaction of the ligand with [RuCl 2 ( 6 -p-cymene)] 2 affords the new water soluble complex [RuCl( 6 -p-cymene)(1)] (2) which has been found to be catalytically active in the water/organic solvent biphasic hydrogenation using styrene and 2-cyclohexen-1-one as model substrates. Very conveniently, the iridium based catalytic system is prepared by simply stirring in water [Ir( 4 -COD)Cl] 2 with Na1 (Ir:Na1 molar ratio = 1:4), the resulting solution is catalytically active and appears more efficient than 2. With both the Ru-and Ir-based systems the catalytically active aqueous phases can be used at least three times without loss of activity.
