Synthesis of New Class of Copper(II) Complex-Based FeNi3/KCC-1 for the N-Formylation of Amines Using Dihydrogen and Carbon Dioxide

Amine formylation with CO2 and H2 catalyzed by heterogeneous Pd/PAL catalyst

“…Introducing an organic ligand containing active elements is a common means of achieving the transformation [3]. By targeted interaction with the active metal center [10][11][12][13][14][15][16], the ligand could suppress or increase the ability of the active metal center in certain aspects to finally achieve the accurate mediation of the catalytic performance. Although good results have been achieved by the above methods, the high cost and complicated synthetic pro-cesses of the organic ligands are undesirable from the standpoint of industrial application.…”

Functionalized Silicas for Metal‐Free and Metal‐Based Catalytic Applications: A Review in Perspective of Green Chemistry

“…While zirconyl Schiff base immobilized on amine FS is utilized for the conversion of fructose to 5‐hydrocymethylfurfural, ytterbium(III) anchored on thiol FS is used for the selective conversion of glucose/cellulose to lactic acid . Different metal ions/metal NPs that immobilized on various FSs such as ruthenium(III) on imine FS, palladium(II) on thiol FS, platinum(IV) on carboxylate FS, palladium(II) on pincer ligand FS, cobalt(II) on IL FS, copper(II) on imine FS, copper(II) on melamine FS, gold(I) on NHC FS and RuPd(0) on amine FS have shown the catalytic efficacy in the hydration of nitriles, cyanation of phenyl rings, hydrosilylation, α ‐arylation, acylation of aryl halides FS, oxidative condensation benzyl alcohol and amines, N‐formylation of amines, alkyne functionalization and ether bond cleavage (diphenylether), respectively.…”

“…With the use of 4‐aminoethylpiperidine during the sequential alkylations with cyanuric chloride, the grafting of organic dendrite molecules on silica is achieved . Sodium chloroacetate has been also used for the N‐alkylation with aromatic FS Different to the above reports, research group of S. M. Sadeghzadeh has carried out the nucleophilic substitution on eight chlorine sites of chloropropyloctasilsesquioxane using APTES and successively, the obtained product is anchored on silica …”

“…The significance of core‐shell materials in catalysis is well discussed in the other review article published by M. B. Gawande et al . To form the core‐shell structure with FSs, the different magnetic materials such as Fe 3 O 4 , FeNi 3 , γ ‐Fe 2 O 3 and NiFe 2 O 4 have been employed. For the magnetic FS composite that does not have the core‐shell structure, the agglomeration of the magnetic nanoparticles is inevitable …”

Active catalyst construction for CO2 recycling via catalytic synthesis of N-doped carbon on supported Cu

“…To substitute the toxic carbon monoxide, the reductive coupling of dimethylamine with CO 2 and H 2 would offer a fascinating route for sustainable production of DMF. Since the initial report by Haynes et al on (Ph 3 P) 2 (CO)IrCl catalyzed preparation of DMF from dimethylamine with CO 2 and H 2 in 1970 7 , a series of homogeneous and heterogeneous transition-metal catalysts, such as ruthenium 8–11 , palladium 12–14 , platinum 15 , iridium 16 , iron 17,18 , copper 19–22 , and others 23–25 , are developed for the reduction of CO 2 to synthesize DMF. Although it has been extensively studied, the highly controlled synthesis of DMF remains a tremendous challenge because DMF is prone to further reduction into N(CH 3 ) 3 26 .…”
