In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 14871-92-2,(2,2¡ä-Bipyridine)dichloropalladium(II), as follows.14871-92-2

Mefenamic acid (0.40 mmol) was dissolved in methanol (15 mL) followed by the addition of KOH (0.40 mmol). After 60 min of stirring, the resulting solution was slowly added to an aqueous solution of [PdCl2(bipy)] (0.20 mmol). After 40 min of constant stirring, the yellow solid obtained was collected by filtration, washed with ethanol and dried in a desiccator with P4O10. The yield was 63%. Anal. Calc. for [Pd(C15H14NO2)2(bipy)] (%): C 64.6; H 4.88;N 7.54. Found: C 63.3; H 4.74; N 7.62. The complex is soluble inchloroform and insoluble in water and DMSO. As already observed for the Pd-tra complex, no single crystals were obtained to perform an X ray structural characterization. The [PdCl2(bipy)] complexused as a precursor in the synthesis of Pd-mef was synthesized as described in the literature [21].

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 14871-92-2, We look forward to the emergence of more reaction modes in the future.

General procedure: [Pd(bpy)Cl2] (0.20 g, 0.60 mmol) was suspended in water (25 mL). Silver nitrate (0.20 g, 1.19 mmol) in water (5 mL) was added and the reaction mixture was stirred for 6 h at 60 C and then at room temperature, always in absence of light. The resulting solution was centrifuged and filtered to remove AgCl. A few drops of water, glycolic acid (0.05 g, 0.66 mmol) and 1 M NaOH (1.20 mL) were added to the filtrate. The resulting solution was stirred for 5 days and concentrated at 60 C to 5 mL on a rotary evaporator. The mixture was cooled to room temperature and the yellow powder was filtered off and dissolved from water and again concentrated to 5 mL. Yellow single crystals suitable for X-ray diffraction were obtained from the resulting solution by slow evaporation at room temperature.
