The works about synthesis of porphy

The works about synthesis of porphyrin lanthanide complexes, both hydrophobic tetraarylporphyrins, Wong et al. (1974), and water-soluble, Horrocks and Hove (1978), were started at the end of the XX century. In these studies the incorporation of Yb and Er was made by heating of a porphyrin and ytterbium acetylacetonate in a microwave oven. A mix of solvents 1,2-dichlorbenzene and distillated dimethylformamide were used in the ratio (1:9) with an addition of dry lithium chloride. The reaction time was 15-20 min., the temperature of the oven was 145 °C, and the power was 650 w. After cooling, solvents were removed by pumping out of the reaction chamber. Metallocomplexes were separated one from another by preparative chromatography on aluminum oxide of II activity degree or on 5/40 μm silica gel. As a result of the synthesis metalloporphyrin Yb and Er -complexes were obtained with an yield of 58.4% and yield 58.7% respectively, Gorshkova et al. (2014).

In these studies the incorporation of Yb and Er was made by heating of a porphyrin and ytterbium acetylacetonate in a microwave oven. A mix of solvents 1.2-dichlorbenzene and dimethylformamide distillated were used in the ratio (1:10) with an addition of dry lithium chloride. The reaction time was 15-20 min., the temperature of the oven was 145° C, and the power was 650 w. After cooling, the solvents were removed by pumping out of the reaction chamber. Metallocomplexes were separated one from another by preparative chromatography on aluminum oxide of II degree activity or on 5/40 μm in silica gel.

The synthesis of porphyrin works about lanthanides complexes, cả hydrophobic tetraarylporphyrins, Wong et al. (1974), and water-soluble, Horrocks and Hove (1978), at the end khởi là of the XX century. In These studies of Yb and Er the incorporation was made by heating of a porphyrin and ytterbium acetylacetonate in a microwave oven. A mix of solvents 1,2-là dichlorbenzene and distillated dimethylformamide used in the ratio (1: 9) with an addition of dry lithium chloride. The reaction time was 15-20 min., The temperature of the oven was 145 ° C, and the power was 650 w. After cooling, solvents là unaligned by pumping out of the reaction chamber. Separated one from another là Metallocomplexes by preparative chromatography on aluminum oxide of second degree activity or on 5/40 micron silica gel. As a result of the synthesis metalloporphyrin Yb and Er -complexes là thu được 58.4% with an yield of 58.7% and yield respectively, Gorshkova et al. (2014).
