T 4144 PROCESS FOR HALOGENATING CYCLOBUTENOARENES The invention relates to a process for preparing a cyclobutenohaloarene comprising the steps of: (a) providing a reaction mixture comprising an organic phase and an aqueous phase, the organic phase comprising a cyclobutenoarene; (b) contacting in the organic phase the cyclobutenoarene and a halogen source under reaction conditions effective for producing a reaction product comprising the cyclobutenohalonrene and hydrogen halide and for permitting migration of the byproduct hydrogen halide into the aqueous phase; and (c) recovering the cyclobutenohaloarene from the organic phase.
