Process for the preparation of halo-substituted benzenes |
abstract |
The invention relates to a process for the preparation of compound of formula (I) wherein R 1 is halogen and R 2 is halogen or hydrogen; comprising a) reacting the compound of formula (II) in an aprotic organic solvent in the presence of an aprotic polar co-solvent with a magnesium amide base followed by a halogenating agent, to the compound of formula I wherein R 1 is halogen and R 2 is hydrogen, and b) reacting the compound of formula (I), wherein R 1 is chloro and R 2 is hydrogen, in an aprotic organic solvent in the presence of an aprotic polar co-solvent with a magnesium amide base followed by a halogenating agent to a compound of formula I, wherein R 1 is chloro and R 2 is halogen. |
