3% 2C3% 27-dibromo-2% 2C2% 27-bipyridine is a commonly used intermediate in organic synthesis. There are many synthesis methods, which are described in detail below.
One is prepared from 2-pyridyl boronic acid and 3-bromo pyridine by Suzuki coupling reaction. This reaction requires the participation of palladium catalysts such as tetra (triphenylphosphine) palladium (0), and bases such as potassium carbonate. In a suitable organic solvent, such as a mixed solvent of dioxane and water, heated and stirred, the two are coupled to form a 2% 2C2% 27-bipyridine derivative. After the bromination step, N-bromosuccinimide (NBS) is used as a brominating agent. In a suitable solvent such as carbon tetrachloride, bromine atoms are introduced at 3% 2C3% 27 under the action of light or an initiator to obtain the target product.
The second can be started from 2-chloropyridine, through a metallization reaction, such as interacting with n-butyl lithium, to generate a corresponding lithium reagent, and then reacting with 3-bromopyridine to form a 2% 2C2% 27-bipyridine skeleton. Subsequent bromination is also carried out with NBS to obtain 3% 2C3% 27-dibromo-2% 2C2% 27-bipyridine.
Another method is to construct the target molecule by multi-step reaction using pyridine as the starting material. For example, pyridine is first electrophilic substitution reaction, suitable substituents are introduced, and then a series of reactions such as coupling and cyclization are used to gradually build the bipyridine structure, and finally 3% 2C3% 27 bromide is achieved to achieve the purpose of synthesis.
All synthesis methods have their own advantages and disadvantages. It is necessary to choose carefully according to actual needs, considering factors such as the availability of raw materials, the difficulty of reaction conditions, the yield and cost, etc., to achieve the ideal synthesis effect.

3% 2C3% 27 -dibromo-2% 2C2% 27 -bipyridine is a chemical substance, its physical properties are as follows:
This substance is in a solid state at room temperature, and its color is mostly white to light yellow crystalline powder. Under the light, it may occasionally glow a little, such as when the sun shines on the frost crystals after the snow in winter, and the sun shines brightly. Its texture is delicate, like a finely ground powder, and it feels smooth to the touch.
When it comes to the melting point, it is about 120-124 ° C, just like the critical point where the spring cold gradually fades and the ice and snow melt. When it encounters this heat, it slowly converts from a solid state to a liquid state. The boiling point information has not yet been conclusively determined, because under conventional conditions, its melting point characteristics are more studied.
In terms of solubility, it has good solubility in common organic solvents such as chloroform, dichloromethane, and acetone, just like a fish entering water and swimming freely. In chloroform, stirring for a while, it quickly dissolves to form a uniform and transparent solution; in dichloromethane, the dissolution rate is slightly slower, but it can also be completely integrated. However, in water, the solubility is poor, such as oil floating in water, and it is difficult for the two to blend.
In terms of density, although there is no accurate data, according to the analogy between chemical structure and similar substances, it can be known that its density is slightly larger than that of water. If it is put into water, it will sink to the bottom like a stone and slowly settle. < Br >
Its stability is acceptable, and it can be stored for a long time in an environment of room temperature and pressure, protected from light and moisture, and not easily deteriorated. However, when encountering strong oxidizing agents, strong acids and alkalis, such as a weak body encountering strong wind and rain, the structure is easily damaged and chemical reactions occur.
