In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact.14871-92-2,(2,2¡ä-Bipyridine)dichloropalladium(II), it is a common compound, a new synthetic route is introduced below.14871-92-2
To a vigorously stirred solution of BzpheH2 (32.32 mg,0.12 mmol) in 8 mL CH3OH/H2O (V:V D 1:1), [Pd(bipy)Cl2] (20 mg, 0.06 mmol) was added. The mixture was heatedto 50C and adjusted to pH D 8-9 by NaOH solution, andthen stirred for 2 h. The solution was concentrated to about80% of the original volume. The complex I-a was separatedfrom the solution after a few days. Yellow crystalline, yield: 68%.

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 14871-92-2, other downstream synthetic routes, hurry up and to see.
