Zirconium based porous coordination polymer (PCP) bearing organocatalytic ligand: A promising dual catalytic center for ultrasonic heterocycle synthesis

A decennary update on applications of metal nanoparticles (MNPs) in the synthesis of nitrogen- and oxygen-containing heterocyclic scaffolds

“…409 The Zr-dependent porous coordination polymer ligated with amino-terephthaline (Zr-PCP-NH 2 )-catalyzed ultrasoundmediated synthesis of 2-phenyl benzimidazoles (83h), and 1,2disubstituted benzimidazoles (85k) was reported recently by Mahmoudi et al via the cyclocondensation of o-phenylene diamines with aryl carbaldehydes (21a) (Scheme 231). 410 The yields of 83h and 85k were found to be higher under ultrasonic conditions rather that high speed stirring conditions. However, they did not compare the present non-selective protocol with selective methodology for the synthesis of 85k previously reported by Chakraborti et al under aqueous conditions.…”

Fe3O4@MCM‐41@ZrCl2: A novel magnetic mesoporous nanocomposite catalyst including zirconium nanoparticles for the synthesis of 1‐(benzothiazolylamino)phenylmethyl‐2‐naphthols

“…In spite of significant advances in the field of mesoporous materials and the growing expansion of new types of them, [1][2][3][4][5][6][7][8] the first and foremost member of M41S called MCM-41 still has attracted growing research attention owing to its chemical versatility. [9][10][11][12][13] Its capabilities, especially in the field of catalytic activity, all come from its unique properties, such as high surface area ($1000 m 2 g −1 ), narrow pore size distribution, uniform pore size, and the possibility of adjusting the diameter of the pores between 2 and 10 nm.…”

Rapid Removal of Mercury from Water by Novel MOF/PP Hybrid Membrane

“…MOFs (metal-organic frameworks) are porous crystalline materials with high surface areas, tunable pore size and functional groups, exhibiting great advantages in the fields of catalysis, separation and adsorption [9][10][11]. Various functionalized MOF materials have been synthesized [12,13]; among them, thiol/thio-functionalized MOFs are considered one Nanomaterials 2021, 11, 2488 2 of 9 of the most effective adsorbents for mercury [14,15].…”
