1-Bromo-2-fluoro-3,5-dimethylbenzene is one of the organic compounds. Its molecule contains bromine atom, fluorine atom and dimethyl, and this unique structure gives it special chemical properties.
Looking at its reactivity, this compound often appears in nucleophilic substitution reactions due to the good departure of bromine atoms. Nucleophilic reagents can attack the carbon atoms attached to the bromine atom, replacing the bromine atom to form a new compound. For example, if sodium alcohol is used as a nucleophilic reagent, the oxygen anion will attack the bromine atom connected to the carbon, and the bromine ion will leave, resulting in ether compounds.
Fluorine atoms have high electronegativity, which will affect the density distribution of electron clouds in the phenyl ring. It decreases the electron cloud density of the benzene ring, especially in the ortho and para-sites, which decreases the activity of the electrophilic substitution reaction of the benzene ring. However, due to its induction effect, under certain conditions, it can also guide the electrophilic reagents to attack specific positions of the benzene ring.
Besides, methyl, which is a power supply subgroup, can increase the electron cloud density of the benzene ring, making the benzene ring more susceptible to electrophilic attack. In the electrophilic substitution reaction, methyl belongs to the ortho and para-locator, which prompts the electrophilic reagents to mainly attack the methyl ortho and para-sites.
