l–aspartic acid chelan–Cu (II) complex coted on ZrFe2O4 MNPs catalyzed one–pot annulation and cooperative geminal-vinylogous anomeric–based oxidation reactions

Nanomagnetic tetraaza (N4 donor) macrocyclic Schiff base complex of copper(ii): synthesis, characterizations, and its catalytic application in Click reactions

“…Keeping in mind that the ligand and linker components are diamagnetic in nature and decrease the MS value, it is worth mentioning that the elemental Cu (II) is paramagnetic because of the necessity of unpaired electrons in their orbitals (configuration is [Ar]3 d 9 ) and increases the MS value of the final complex. 57 Nevertheless, the super magnetic properties and high MS value of the [Fe 3 O 4 @TAM-Schiff-base-Cu (II) ] complex meant that it could be easily isolated from the reaction mixture with the application of a simple external magnet.…”

Magnetic nanoparticles modified with a copper(i) complex as a novel and efficient reusable catalyst for A3 coupling leading to C–N bond formation

“…1, the observed shift in the CN characteristic peak from 1636 cm −1 to 1616 cm −1 confirms the successful complexation of Cu ions with the immobilized BIm–Pyrim ligand on the surface of Fe 3 O 4 nanoparticles (link CuI with a bond). 47–49…”

Efficient and biocompatible new palladium-supported boehmite nanoparticles: synthesis, characterization and application in Suzuki–Miura and Mizoroki–Heck coupling reactions

“…The development and expansion of efficient and useful carbon-carbon bond formation methods is a performance character in the synthesis of organic compounds. [11][12][13][14][15][16][17][18][19] Some of the most frequently used reactions of carbon-carbon bond formation in organic synthesis are Mizoroki-Heck, Sonogashira, Suzuki-Miyaura, Stille, Negishi, etc. [20][21][22][23][24][25][26][27][28][29][30] Among them, the Suzuki reaction is known as the main and general process in the synthesis of biaryls, and palladium compounds usually catalyze this reaction, which includes phenylboronic acid or its derivatives coupling with various aryl halides.…”
