- Practical and metal-free electrophilic aromatic halogenation by interhalogen compounds generated in situ from N-halosuccinimide and catalytic TMSCL
-
Halomonochloride compounds (ClCl, BrCl, ICl) generated in situ from N-halosuccinimide and catalytic chlorotrimethylsilane (TMSCl, 0.1 equiv) can efficiently halogenate aromatic compounds to give halogenated products in good to excellent yields and selectivities. The reaction can be carried out at room temperature or at lower temperatures, requires only one hour, is practical to apply to a wide range of substrates, and provides a simple access to a variety of haloarene compounds.

- METHOD FOR PRODUCING 4-HALOCATECHOL COMPOUND
-
Disclosed is a method for producing a 4-halocatechol compound, which is characterized in that a catechol compound is reacted with 1,3-dihalo-5,5-dimethylhydantoin. Also disclosed are a high-purity 4-chloromethylenedioxybenzene which is characterized in that the methylenedioxybenzene content is not more than 0.5% by mass and the 4,5-dichloromethylenedioxybenzene content is not more than 0.5% by mass, and a method for producing such a high-purity 4-chloromethylenedioxybenzene.
