The article was titled 《A new A3B zinc(II)-porphyrin ligand and its ruthenium(II) complex: synthesis, photophysical properties and photocatalytic applications》.HPLC of Formula: 30414-53-0 The article contains the following contents:
Porphyrins and metalloporphyrins (or porphyrin coordination complexes) have been wildly investigated as photocatalysts in recent years. Herein we synthesized two new A3B porphyrins, a new asym. A3B zinc-porphyrin ligand with peripheral chelate group (pyridine dicarboxylate), and a ruthenium(II) complex of the porphyrin ligand. Their photo-phys. properties were characterized and investigated by UV-visible and fluorescent emission. The modeling of the mol. structures was optimized by DFT theor. calculation All porphyrin compounds exhibited strong absorbance at the Soret bands and Q bands. The free base of porphyrin possessed a higher quantum yield and a longer life time than the other two zinc-porphyrins and ruthenium-porphyrin in terms of fluorescence. Furthermore, the ruthenium-porphyrin complex can be used as a promising photocatalyst under visible light for two kinds of organic reactions: ketone-related oxidative aminothiocyanation (above 90% yield) and indole-related oxidative thiocyanation (around 80% yield) with a remarkable low amount (0.1 mmol %). In the experiment, the researchers used Methyl 3-oxovalerate(cas: 30414-53-0HPLC of Formula: 30414-53-0)
Methyl 3-oxovalerate(cas: 30414-53-0) belongs to ketone compounds. Ketone compounds have important physiological properties. They are found in several sugars and in compounds for medicinal use, including natural and synthetic steroid hormones. Molecules of the anti-inflammatory agent cortisone contain three ketone groups.HPLC of Formula: 30414-53-0
