Abstract :
Iron(III) supported on nano silica as a new
catalyst has been synthesized. Structural properties of this
complex have been studied by TEM, SEM and EDX. The
average crystalline size of Iron(III) supported on nano
silica is 30–50 nm. Catalytic activity of this catalyst has
been investigated by synthesis of benzimidazoles from 1,
2-diaminobenzene and aromatic aldehydes, and also the
other variables investigated such as the amount of catalyst,
reaction temperature and the effect of various solvents are
also studied. The present procedure offers several advantages such as short reaction time, simple workup, recovery
and reusability of the catalyst.
