“…An assessment of FT-IR spectra of TPA-POP, starting materials shows absorption band at 1370 cm −1 due to the P=N bond ( Figure 1). [24] Also, the frequency of the P-N single-bond stretching vibration has been assigned at 770 cm −1. [25] The strong infrared bands at 1170 cm −1 in the TPA-POP compound was assigned to C-N stretching vibrations.…”

A novel triazine‐phosphanimine polymeric organic support (TPA) was synthesized successfully by a controllable one‐pot method using melamine (1,3,5‐triazine‐2,4,6‐triamine) and trichlorophosphane (PCl3). The TPA substrate is a material incorporating P and N atoms which can coordinate with metals as a pincer ligand to stabilize them, providing an efficient heterogeneous support to prepare recyclable transition metal catalyst systems. In this study, TPA was used as support to immobilize iridium nanoparticles in the range of ~8 nm on its surface, resulting in the generation of a novel iridium nanocatalyst system (INP‐TPA‐POP). This catalyst system was characterized using different microscopic and spectroscopic techniques such as FT‐IR, TEM, XPS, XRD, SEM, EDX, elemental analysis, ICP and BET analysis. The INP‐TPA‐POP nanocatalyst exhibited remarkable activity in reduction of aldehydes to alcohols using formic acids as reducing agent in ethanol as solvent.

“…In the structure of this catalyst, system l-cysteine moieties were chemically grafted to the surface of magnetic nanoparticles, creating efficient amino acid-based catalytic sites to be used in organic reactions. In this study and in continuation of over previous works on magnetic nanoparticle-based catalyst systems [47][48][49][50][51][52][53][54], we would like to show the catalytic applicability of this LCMNP in another MCR for efficient synthesis of a class of xanthene derivatives.…”

Carbon‒carbon (C‒C) and carbon‒heteroatom (C‒X) bonds that form via transition-metal-catalyzed processes have been extensively used in the organic synthesis and preparation of natural products and important compounds such as heterocycles, biologically active molecules, and dendrimers. Among the most significant catalysts, magnetic nanoparticles-supported palladium complexes are very effective, versatile, and heterogeneous catalysts for a wide range of C‒C and C‒X coupling reactions due to their reusability, thermal stability, and excellent catalytic performance. In this review, recent advances to develop magnetic nanoparticles supported palladium complexes, including their preparation, characterization, catalytic application, and reusability in the formation of both C‒C and C‒X bonds, by authors such as Sonogashira, Heck, Suzuki‒Miyaura, and Stille, and a few examples concerning N-arylation, S-arylation, and Csp2-P coupling reactions are discussed.
