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].
At the same time, in my other blogs, there are other synthetic methods of this type of compound, (2,2¡ä-Bipyridine)dichloropalladium(II), and friends who are interested can also refer to it.
