Abstract

NiII(BAPTE)(NO3)2-Cell as a novel cellulose supported catalyst has been prepared and characterized by various techniques including FT-IR, XRD, SEM, TGA and EDX.

Synthesis and characterization of thiophene-derived palladium(ii) complex immobilized on FSM-16 and its application in the novel synthesis of 7-(aryl)-7,12-dihydro-6H-indeno[1,2,4]triazolo[1,5-a]pyrimidine-6-one derivatives

“…Furthermore, they are widely used in materials, such as semiconductors and nonlinear optical properties of organic photovoltaic systems. [61][62][63] As a follow-up to our research program for the synthesis of new recyclable heterogeneous nanocatalysts, [64][65][66][67][68][69][70][71] our attention was focused on FSM-16, which serves as a support for the immobilization of palladium complexes (Scheme 1). The FSM-16-based catalyst, also known as FSM-16@Imine-Thiophen/Pd, was used in the multi-component reactions of indan-1,3dione, aromatic aldehydes and 3-amino-1H-1,2,4-triazole to produce indeno-1,2,4-triazolo[1,5-a]pyrimidine derivatives.…”

A novel ionic liquid immobilized on FSM-16: a novel recoverable nanocatalyst for the synthesis of biscoumarin derivatives

“…Many drugs also contain the coumarin structure, including phenprocoumon, tioclomarol, warfarin (anticoagulant), novobiocin (antibiotic), hymecromone (antispasmodic), cloricromen (platelet aggregation inhibitor), ensaculin (treatment for dementia), ethyl biscoumacetate (vitamin K antagonist), and aminocoumarin (antibiotic). [43][44][45][46][47][48][49] Continuing our program to develop new methodologies for the preparation of green heterogeneous catalysts, [50][51][52][53] in this study, we report the preparation, characterization, and catalytic application of FSM-16-IL-SO 3 H as a novel Brønsted acidic ionic liquid and a reusable catalyst. The prepared catalyst was employed in the synthesis of biscoumarin derivatives via the reaction between aromatic aldehydes and 4-hydroxycoumarin.…”

Ionic liquid immobilized on modified magnetic FSM-16: an efficient and magnetically recoverable nanocatalyst

“…Polyhydroquinoline derivatives are usually synthesized via the four-compound one-pot reaction of aldehyde, dimedone, ethyl acetoacetate, ammonium acetate, and the corresponding catalyst. [49][50][51] In continuation of our studies program for the synthesis of novel heterogeneous nanocatalysts and also considering the importance of mesoporous materials in the catalysis synthesis process, 12,[52][53][54][55][56][57][58] herein, a recyclable magnetic catalyst based on FSM-16 (Fe 3 O 4 @FSM-16-SO 3 /IL) has been synthesized and characterized. Furthermore, Fe 3 O 4 @FSM-16-SO 3 /IL was used as an effective catalyst in the synthesis of polyhydroquinoline derivatives via the one-pot reaction of various aromatic aldehydes, dimedone, ethyl acetoacetate, and ammonium acetate.…”
