uct was formed using benzylmagnesium chloride (Entry 9, Table 2)
chloride (Entry 1, Table 2) upon reacting with CCl4 gave trace
amount of four-chlorine-substituted product along with disub-
stituted and trisubstituted products. Hexylmagnesium chloride
(Entry 3, Table 2) and octylmagnesium chloride (Entry 5, Table 2)
preferably gave disubstituted products even though very small
quantities of tetrasubstituted products were also observed. Syn-
thesis of such tetrasubstituted carbon center is of great importance
and so further study is being done to explain it.

Reactions of CH2Cl2 and CHCl3 showed better multiple C Cl
bond substitution with the use of Grignard reagents having bulky
aromatic groups such as phenyl groups. Entry 1 in Table 2 shows
the reaction yields of CH2Cl2, CHCl3 and CCl4 when reacted with
butylmagnesium chloride at room temperature. Cross coupling of
64% of CH2Cl2 was observed within 20 min in presence of 0.4 mol%
of 2 with the TOF of 463 h−1 whereas a TOF of 724 h−1 was observed
for the cross coupling of butylmagnesium chloride with both CHCl3
and CCl4.

A nickel(II) pincer complex (2) with a sterically bulky triden-
tate ligand was synthesized, characterized, and used as a cross
coupling catalyst. The nickel(II) complex enables multiple C Cl
bond activation in CH2Cl2, CHCl3 and CCl4, for cross couplings
with multiple Grignard reagents at room temperature in less than
20 min. The complex (2) showed much improved activity over
that previously reported for the activation of multiple C Cl bonds
for C C bond forming cross coupling reactions with Grignard
reagents. The method could prove valuable to remediate toxic
chlorinated solvents while producing value added products, under
mild reaction conditions. Increase in temperature and Grignard
reagent generally resulted in increased cross-coupling products
formation yields with little change in selectivity toward any one
product. Catalyst activity reached TOF of 724 h−1 with catalyst load-
ing of only 0.4 mol%. Such high catalytic activity is unknown in
the literature for cross-coupling reaction involving polychlorinated
alkanes.
