Preferential alkylation or acylation of meta-disubstituted benzenes |
摘要 |
In a mixture of isomers of a disubstituted benzene such as dichlorobenzene, the meta-disubstituted isomer is preferentially reacted with an alkylating or acylating agent, e.g., an alkyl halide, by contacting the mixture with the agent in the presence of a Friedel-Craft catalyst at a temperature of less than about 60 DEG C.
