Green one-pot synthesis of 2H-indazolo[2,1-b]phthalazine-triones: a comparative study of heterogeneous solid acid catalysts with magnetic core

FNAOSiPPEA[]/Zn(II) as a Bifunctional Lewis Acid/ Bronsted Base Heterogeneous Magnetic Nanocatalyst Based on Nano‐Almond Shell for Synthesis of Naphtho[1,3]oxazine Derivatives**

“…Magnetic nanoparticles (MNPs) have expanded in recent years due to their special physical and chemical properties such as high surface area, and high penetration power, [1,2] The instability of Fe 3 O 4 nanoparticles is still a major challenge in nanoparticles science. For this reason, the surface of magnetic nanoparticles has been modified by coating them with nano‐cellulose, ionic liquids, silica nanoparticles, and polymers [3–9] . Nano‐cellulose (NC) has been reported as coating for magnetic nanoparticles due to their high O−H functional groups.…”

[3][4][5][6][7][8][9] Nano-cellulose (NC) has been reported as coating for magnetic nanoparticles due to their high OÀ H functional groups. NCs are abundant biopolymers that can be extracted from bacteria, algae, wood, cotton, and agricultural residues.…”

Pd(0)‐guanidine@MCM‐41: a very effective catalyst for rapid production of bis (pyrazolyl)methanes

“…Nanocatalysis is one of the most exciting subfields to have emerged from nanoscience. [1][2][3][4][5][6][7] Its central aim is the control of chemical reactions by changing the size, dimensionality, chemical composition and morphology of the reaction center, and by changing the kinetics using nanopatterning of the reaction centers. [8][9][10][11][12] Nanoparticles can substitute conventional materials, and serve as active and stable heterogeneous catalysts or as support materials for various catalytic groups.…”
