Reference of 789-25-3, The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 789-25-3, Name is Triphenylsilane, SMILES is [SiH](C1=CC=CC=C1)(C2=CC=CC=C2)C3=CC=CC=C3, belongs to phthalazine compound. In a article, author is Magyari, Jozef, introduce new discover of the category.
New coordination compounds have been synthesized by reacting Zn(II) and Co(II) nitrate or acetate in the presence of triethylamine with Schiff-base ligands containing diazine-ring, pyridine-2-carbaldehyde phthalazine-1-hydrazone,HzPYH, and di(2-pyridyl)ketone 3-chloro-pyridazine-6-hydrazone,HpDPKH. Complexes of[Co(HzPY)(2)]center dot 3.4H(2)O,[Zn(HzPY)(2)]and[Co(HpDPK)(2)]NO3 center dot H(2)Owere obtained. The crystal and the molecular structure of[Co(HzPY)(2)]center dot 3.4H(2)Owere determined using X-ray diffraction structure analysis. The compounds were characterized by elemental analysis, FT-IR and UV-Vis spectral data, conductivity and magnetic measurements, too. Except for the diamagnetic Co(III) compound with a nitrate counter-ion,[Co(HpDPK)(2)]NO3 center dot H2O, all the complexes are neutral-type. The magnetic moment of[Co(HzPY)(2)]center dot 3.4H(2)Oindicated a low-spin octahedral complex which is relatively rear amongst octahedral Co(II) complexes. Hence, its magnetic moment was measured in the temperature range of 3-300 K. To obtain products in the form of single crystals and/or to increase the yield, the reactions were carried out in solutions with different solvents or recrystallized from solvent mixtures. To determine the nature of the solvent (if any) in the crystalline products and to gain better insight into the decomposition mechanism, coupled TG-MS measurements were carried out. The desolvated compounds were stable at relatively high temperatures (> 200 degrees C). The cytotoxic, antiproliferative and efflux pump inhibitory effects of the compounds were tested in multidrug-resistant mouse T-lymphoma cells to study their effect on the suppression of MDR. The antibacterial activity of the compounds was also tested. The results of the antibacterial tests were analysed to understand better the effect of the central atoms and the structure on a specific activity.
