Classification of ordered mesoporous materials M41S into three groups of hexagonal phase included MCM-41 and FSM-16, cubic phase named MCM-48 and unstable lamellar phase recognized MCM-50 reported in literature.1 FSM-16, due to their thicker pore walls, in comparison
with MCM-41 has a higher thermal and hydrothermal stability. For this reasons, we focused on FSM-
16 which act as hosts to immobilize a new metal complexes and synthesis a new catalyst.2
1, 3-diaza-2,4-cyclopentadiene compounds which known as imidazole, have two N
heteroatom.3 These compounds have wide utilities in various fields for example in pharmacy,
biological systems also in chemistry such as use as ionic liquids for synthesis of organometallic
catalysis and N-heterocyclic carbenes.4
In this way, for the development of new practical method, we designed a new catalyst system.
This organometallic catalyst, based on FSM-16, named as FSM-16@CPTMS-Rh-Ni and applied for
multi component reaction such as synthesis of 2,4,5-triaryl-1H-imidazoles and 1,2,4,5-tetrasubstituted
imidazoles (Scheme 1).
