N-CHLORO-2,3,4,4,5,6-HEXACHLOROCYCLOHEXA- 2,5-DIENYLIDENEAMINE AS A MILD AND HIGHLY REGIOSELECTIVE CHLORINATING REAGENT

N-Chloro-2,3,4,4,5,6-hexachlorocyclohexa-2,5-dienylideneamine was used as a new, mild and highly regioselective chlorinating reagent in the chlorination of phenol and o-cresol in CCl4, DMF and CH3CN. The effects of C2H5OH, C5H5N, DMF and Et3N on the regioselectivity in CCl4 have also been examined.
