Ni-Rhodanine Complex Supported on FSM-16 as Mesoporous Silica Support: Synthesis, Characterization and Application in Synthesis of Tri and Tetrasubstituted Imidazoles and 3,4-Dihydropyrimidine-2-(1H)-Ones

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

“…2d, the shifted imine band to a lower frequency in the FSM-16@Imine-Thiophen/Pd nanocatalyst (from 1635 cm −1 to 1627 cm −1 ), which confirms the formation of palladium complex on the surface of FSM-16@Imine-Thiophen. 11,31–33…”

“…2d, the shied imine band to a lower frequency in the FSM-16@Imine-Thiophen/Pd nanocatalyst (from 1635 cm −1 to 1627 cm −1 ), which conrms the formation of palladium complex on the surface of FSM-16@Imine-Thiophen. 11,[31][32][33] According to Fig. 3, the EDX spectrum of FSM-16@Imine-Thiophen/Pd contains all expected elemental cases, including C, O, N, S, Si, Pd, and Cl elements.…”

“…Some recently studied FSM-16 catalysis systems are Fe 3 O 4 @FSM-16-SO 3 H, FSM-16/AEPC-SO 3 H, FSM-16-SO 3 H, and FSM-16-Met. [30][31][32][33] Furthermore, FSM-16 materials have various uses in photo-metathesis reactions. Consequently, the development of synthetic procedures that yield novel heterogeneous FSM-16-based catalysts is still a great challenge for researchers.…”

Recent progress in the synthesis of azoles and related five‐membered ring heterocycles using silica‐supported heterogeneous catalysts

“…The reaction was optimized under solvent-free conditions and a series of tri-and tetrasubstituted imidazole derivatives were synthesized satisfactorily. Some of the major features of this protocol are short reaction times, solvent- S C H E M E 1 9 Synthesis of triazoles by using magnetic silica sphere grafted sulfonic acid (MSS-SO 3 H) free conditions, reusability, and satisfactory yield (Figure 3) [41].…”

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

“…[3][4][5][6][7][8] FSM-16 structures have been prepared by intercalation of quarterly ammonium surfactant as a template into layered sodium silicate, kanemite, followed by calcination to remove the template, resulting in the formation of a hexagonal arrangement of channels with active surface silanol groups, high surface area, and uniform pore size. [9][10][11] Some important studies reported on the FSM-16 based nanocatalysts are FSM-16@imine-thiophen/Pd, 12 Fe 3 O 4 @FSM-16-SO 3 H, 13 FSM-16-Met, 14 FSM-16-SO 3 H, 15 and FSM-16/AEPC-SO 3 H. 16 Although porous nanomaterials have been widely used as supports for the preparation of heterogeneous catalysts, one of the major problems of them is the difficulty of separation from the reaction mixture by ltration and centrifugation. The key to overcoming these limitations is the use of magnetic nanoparticles (MNPs), which allow easy and faster separation of the porous nanomaterials from the reaction mixture by an external magnetic eld.…”
