| introduction | 2,2 '-bisbrominobenzene has a white or off-white solid powder appearance at normal temperature and pressure, and can be used as an intermediate in organic synthesis. It is a commercial organic synthon, which has good solubility in common organic solvents such as dimethyl sulfoxide, N,N-dimethylformamide, ethyl acetate, dichloromethane, and chloroform. But it has poor solubility in water. |
| Uses | 2,2 '-bisbromobiphenyl is a commercial organic synthon, the main purpose is to participate in organic luminescent materials as a molecular skeleton And the construction of conjugated macromolecules. The two bromine atoms in its structure can undergo Suzuki coupling reactions separately and in batches, and can also couple the two bromine atoms in one step at the same time to form a conjugated structure of the ring. |
| synthesis method | for the synthesis of 2,2 '-bis-brominobenzene, the most practical method is also the most used starting from o-dibromobenzene and stirring at low temperature under the action of n-butyl lithium to obtain the target product. The reaction is simple and efficient, and the post-treatment is relatively simple. It should be pointed out that the reaction may be an intermediate that has experienced a benzyne. |
