Process for the production of chloroaromatics |
| abstract |
Method for the prepn. of chlorinated aromatic cpds. of formula (I) comprises heating chloroformic acid esters of formula (II) in the presence of an inert organic solvent and a catalytic amt. of one or more Lewis acids chosen from aluminium-, iron- or antimony halides at 90-240 deg C in the liq. phase. R<1> = 1-6C alkyl; R<2> = H or 1-6C alkyl; and R<3> = H, 1-6C alkyl, F, Cl or Br. |
