Agilent 6890 gas chromatograph fitted with a 30 m × 0.25
mm DB-5MS capillary column (Agilent Corporation)
in tandem with an Agilent 5975 inert mass-selective
detector was employed for these measurements. After
each hour of electrolysis, 1.0 mL of solution was taken
from the H-cell and the supporting electrolyte removed
prior to the GC-MS analysis which was carried out as
described in the literature [34].

CONCLUSION
In summary, the doubly reduced (TPP)FeIIICl and
(OEP)FeIIICl, which are represented as [(Por)FeI]-, can
catalyze the dechlorination of a-hexachlorocyclohexane
(a-HCH) to stepwise generate pentachlorocyclohexene
(PCCH) and tetrachlorocyclohexadiene (TCDN) as
intermediates, prior to generation of the final dechlorination
products which consisted of an isomeric mixture of
trichlorobenzenes (TCB). The experimental data indicate
that (OEP)FeCl is a better catalyst for the reductive
dechlorination of a-HCH as compared to (TPP)FeCl under
the given experimental conditions.
