ABSTRACT:
Process for the preparation of .alpha.-chlorinated chloroformates with the formula ##STR1## where R is H, an aliphatic or aromatic hydrocarbon radical or heterocyclic radical, substituted or non-substituted and n an integer.
The process consists of reacting ClCOOCCl.sub.3 or Cl.sub.3 COCOOCCl.sub.3 with an aldehyde with formula R--(CHO).sub.n in the presence of a compound, which in the medium releases a pair of ions, the anion of which being a halide which can attack the aldehyde function, because of the weak attractive power of the cation of this compound.
