Wang, Jixiao published the artcileUnsupported Nanoporous Palladium Catalyst for N-Formylation of Amines Using CO2 as a Sustainable C1 Source, COA of Formula: C8H11NO, the main research area is formamide green preparation; amine carbon dioxide formylation nanoporous palladium catalyst.

An efficient heterogeneous catalytic system for the synthesis of aryl formamides R1N(C(O)H)R2 [R1 = Ph, 4-MeC6H4, 2-MeOC6H4, etc.; R2 = H, Me, Bn, etc.; R1 = R2 = Ph, Bn, Cy, etc.] via N-formylation of amines using CO2 as a sustainable C1 source was developed using unsupported nanoporous palladium (PdNPore). The PdNPore-catalyzed N-formylation of amines and CO2 with hydrosilane proceeded smoothly under mild reaction conditions to yield formamides in satisfactory to excellent yields. No palladium leached from PdNPore during the hydrogenation reaction. Moreover, the catalyst was easily recovered and reused without any loss of catalytic activity. This study was the first to demonstrate that PdNPore catalyzed CO2 conversion to form C-N bond, which enriches the reaction types of CO2 conversion catalyzed by PdNPore catalyst.

Du, Chongyang published the artcileZinc Powder Catalysed Formylation and Urealation of Amines Using CO2 as a C1 Building Block, Category: isoquinoline, the main research area is formamide preparation; secondary amine carbon dioxide formylation zinc catalyst; urea preparation; primary amine carbon dioxide urealation zinc catalyst.

The zinc powder catalyzed formylation and urealation of secondary amines e.g., N-methylaniline and primary aromatic amines RNH2 (R = Ph, 2,4,6-trimethylphenyl, cyclohexyl, etc.) with CO2 and (EtO)3SiH under solvent-free condition were reported. Using 2 mol% zinc powder as the catalyst, a series of secondary amines, both the aromatic ones and the aliphatic ones can be formylated into formamides e.g., N-methyl-N-phenylformamide. When primary aromatic amines were used as the substrates, the reactions produce urea derivatives RNHC(O)NHR. The electronic and steric effects from the substrates on the formylation and urealation reactions were observed and discussed. The recovery and reusability of zinc powder were investigated, showing that zinc powder can be reused in the formylation reaction without loss of catalytic activity. The anal. on the reactants/products mixture after filtering out the zinc powder showed that zinc concentration in the mixture is low to 1 ppm. The pathways for the formylation and urealation of amines with this catalytic system were also investigated and related to the different substrates.

Gonzalez-Lainez, Miguel published the artcileN-Methylation of Amines with Methanol Catalyzed by Iridium(I) Complexes Bearing an N,O-Functionalized NHC Ligand, Category: isoquinoline, the main research area is iridium complex imidazolylidenelutidine polydentate ligand preparation catalyst methylation aniline; crystal structure iridium complex containing imidazolylidenelutidine polydentate ligand; mol structure iridium complex containing imidazolylidenelutidine polydentate ligand.

A set of neutral [IrBr(L2)(κC-tBuImCH2PyCH2OMe)] and cationic [Ir(L2)(κ2C,N-tBuImCH2PyCH2OMe)]PF6 (L2 = cod, (CO)2) Ir(I) compounds featuring a flexible lutidine-derived polydentate ligand having NHC and -OMe as donor functions were evaluated as catalyst precursors for the N-methylation of aniline using MeOH both as a reducing agent and a C1 source. The carbonyl complexes are somewhat more active than the related diene compounds with the neutral compound [IrBr(CO)2(κC-tBuImCH2PyCH2OMe)] being the more active. A range of aromatic primary amines, including heterocyclic amines, were selectively transformed into the corresponding N-methylamino derivatives using this catalyst at a low catalyst loading (0.1 mol %) and substoichiometric amounts of Cs2CO3 (half equiv) as a base, in MeOH at 423 K. For aliphatic primary amines, selective N,N-dimethylation was achieved under the same catalytic conditions. The unselective deprotonation of the methylene linkers in [IrBr(CO)2(κC-tBuImCH2PyCH2OMe)] affords two isomeric neutral complexes featuring a coordinated dearomatized pyridine core, which were converted into [Ir(OMe)(CO)2(κC-tBuImCH2PyCH2OMe)] upon addition of MeOH. This compound undergoes thermal activation of a C-H bond of the tert-Bu group to give the cyclometalated Ir(I) complex [Ir(CO)2{κ2C,C-(-CH2Me2C-ImCH2PyCH2OMe)}] featuring a bidentate C,C-coordinated NHC ligand. Mechanistic studies support a borrowing H mechanism proceeding through Ir(I) intermediates with the methoxo complex as the catalytic active species and the cyclometalated complex as the catalyst resting state. D labeling experiments demonstrated that both species are in equilibrium under catalytic conditions, which is consistent with the exhibited catalytic activity of the cyclometalated complex.
