![]() ![]() This means that they are a risk-and-reward type of dragon to have on your team: though they take a lot more damage, they can also deal extra damage to any dragon. The first being that Primal Dragons are unique in that, while they are weak to every element in the game, they are also strong against every element too. While Primal Dragons are not as powerful as their Divine or Ancient counterparts, they do still come with some very special features. The characterization of three new complexes was carried out using different analysis techniques such as elemental analysis, IR and UV-visible spectroscopy, magnetic susceptibility, conductivity and mass spectrometry.These cheeky new additions to Dragolandia have only just been discovered! They are rare dragons that can now be collected from various on-going events in the game. The empirical formula of the complexes was for HL1 and HL2 and for H元. ![]() Using microwave irradiation, the copper complexes were obtained in shorter reaction times. Using conventional heating copper(II) acetate dissolved in water, was slowly added in a stirred solution of the corresponding ligand HL1, HL2 and H元 in ethanol for 24 h at 70 ✬. The copper complexes of 4,6-diaryldihydropyrimidinones were prepared by refluxing mixture of copper(II) acetate and the corresponding 3,4-dihydropyrimidine-2(1H)-thione in molar ratio (1:2). The potential use of these complexes have been attracted great interest due to their biological activity as antimicrobial, antiviral, anti-inflammatory and antitumor agents. It has been established that the properties of coppercoordinated compounds are largely determined by the nature of ligands and donor atoms bound to the metal ion. Copper is an essential trace nutrient for organisms. However, microwave synthesis of coordination and organometallic compounds has been less explored. Microwave irradiation has been applied as a non-conventional reaction condition in several areas of chemistry such as organic and polymer synthesis or analytical chemistry. ![]()
