The metal-organic frameworks are a new type of crystalline material with very high porosity and surface area. These frameworks, which are in the category of coordination polymers, are obtained from the bonding of metal ions to organic ligands by coordination bonds. These compounds have different application, such as catalysts, gas adsorbers, drug delivery and as sensors.
Tetrahydrobenzo[b]pyrans and their derivatives are an important part of the heterocyclic compounds, which have medicinal and biological properties, such as anticoagulant, diuretic, anticancer and antianapHylactic activities. Generally 4H-pyran derivatives are synthesized through three-component condensation of different aldehydes, malononitrile and changeable 1,3-dicarbonyl compounds under mild conditions with various catalysts and different synthetic methods. This study reported preparation Cu2(NH2-BDC)2(DABCO) that uses as heterogeneous catalysts for the synthesis of 4H-derivatives that conditions ball mill at room temperature were selected as optimal conditions. (a5 product, 96% efficiency, 5 min duration), as well as MIL100 (Fe) / chitosan nanocomposite that uses as an adsorbent for the removal of organic pollutants such as methylene blue and methyl orange, which, under the conditions of ultrasonic bath, at room temperature In the 2 minute duration were selected as optimal conditions (85% methylene blue removal, 80% methyl orange removal).
