چکیده مقاله :
Polyoxometalate (POM) are anionic metal oxide group with different nuclearizes, sizes, and shapes. Their special features can be mentioned such as high thermal stability, excellent redox abilities, high negative charges, and the to form dynamic structures that can have a size from nano to micro-scale. They represent a new class of molecular systems that have applications in nanotechnology, pharmaceuticals, magnetism, materials science, biology, and catalysis. Polyoxometalate (POM) is a group of anionic clusters of transition metal oxides in their highest oxidation state, which are made through bonding by oxygen atoms, to represent metal-oxo units, where the metal ion is a multifaceted building block [1,2]. Benzothiazoles are some of the most effective heterocyclic organic compounds, which are used as valuable intermediates in organic synthesis. Benzothiazoles derivatives were synthesized from the condensation of aldehydes and 1,2-phenylenediamine with aromatic aldehydes under oxidative or strongly acidic conditions [3]. Herein, we report the design of a [N(C4H9)4]2[[Cr Mo6O18(OH)3] The catalytic efficiencies in the catalytic properties and stabilities of the synthesized catalyst in the preparation of various benzothiazoles were also investigated (Scheme ( Scheme: Synthesis of benzothiazoles catalyzed by [CrMo6O18]
