ABSTRACT
The use of a heterogeneous catalyst in place of a homogeneous sys-
tem in chemical reactions is a sought-after goal because it gives
rise to several advantages. A commonly accepted benefit is the
easy separation of the solid catalyst from the reaction mixture
and the straightforward recovery of it, without affording the time-
consuming, expensive, and sometimes difficult purification tech-
niques adopted for valuable soluble organometallic complexes.
