bromine in the presence of iron powder. The chemical reaction principle is the same as that of chlorination of benzene to produce chlorobenzene. The reaction between bromobenzene and metal magnesium can generate phenylmagnesium bromide, which is a Grignard reagent with important uses in organic ...
Bromobenzene is a colorless, flammable liquid with a density greater than water and with an aromatic odor. It is synthesized by the reaction of bromide with benzene in the presence of iron powder. It is used for organic synthesis, particularly in the production of the intermediate phenylmagnesium...
(479 mg, 1.2 mmol. 4.0 equiv) or pentafluorophenyl bromide (296 mg, 1.2 mmol. 4.0 equiv) and trifluoromethyl benzoate (171 mg, 0.9 mmol, 3 equiv) were capped and allowed to react at room temperature for 12 hours.After the end of the reaction, the F-spectrum yield was first calculated...
The methoxyethoxy group-containing monomer afforded an oligomer with an Mn of 666. The coupling reaction of tetrasubstituted p-dibromobenzenes occurred at a very-low level because of the steric hindrance of the tetra substituents. Polymers 2a–f exhibited high thermal stability, and the ...
PreparationBromobenzene is obtained by reacting benzene with bromine. First add iron powder and benzene into the reactor, slowly add bromine under stirring, keep the reaction at 70-80°C for 1 h after adding, the obtained crude product is washed with water and 5% sodium hydroxide solution, left...
