A series of functionalized ionic liquids (ILs) were developed for the reductive functionalization of CO2 with amine and hydrosilane to afford formamides under mild conditions. It was found that 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU)-based IL i.e. [DBUC12]Br showed high efficiency for the N-formylation reaction of amines without using any organic solvents or additives. Furthermore, control experiments suggested the cations with active hydrogen may weaken the nucleophilicity of anions through ion pairing interactions, thereby affecting the activation of hydrosilane. The reaction mechanism was then investigated by D. Functional Theory (DFT) calculations This protocol represented a highly efficient and environmentally friendly example for catalytic conversion of CO2 into value-added chems. such as formamide derivatives by employing DBU functionalized ILs.

The first examples of iminium catalyzed Nazarov cyclizations of divinyl ketones are presented. Experiments describing hydroxylamine catalysis of the cyclization of eight α-alkoxy divinyl ketones (60-79% yield) and one unactivated divinyl ketone (38% yield) are reported.

In this reaction system, an organoiodine compound was immediately oxidized by Oxone to generate cyclic hypervalent iodine (III) species in-situ, which served as the specific mediator for the selective p-quinone synthesis, preventing o-quinone formation.

Cho, Jin Hee published the artcileA bimetallic PdCu-Fe3O4 catalyst with an optimal d-band centre for selective N-methylation of aromatic amines with methanol, Recommanded Product: 4-Methoxy-N-methylaniline, the main research area is amine methanol methylation; bimetallic palladium copper iron oxide nanoparticle catalyst preparation.

Catalytic methylation utilizing methanol as a sustainable C1 building block and hydrogen source continues to attract attention due to its atom-economical, cost-effective, and simple one-pot method. So far, research on heterogeneous systems has been limited to noble monometallic catalysts such as Ir, Pd, and Pt. A bimetallic catalyst containing a non-noble metal can be an ideal tool to modulate the reactivity and economic feasibility. Reported herein is a bimetallic PdCu-Fe3O4 nanoparticle (NP) catalyst for the selective N-methylation of aniline with methanol as a carbon source in the presence of K2CO3 via a “”hydrogen-borrowing strategy””. The PdCu alloy showed synergistic catalytic activity, superior to monometallic Pd and Cu catalysts. The best catalytic activity for N-methylation of aniline was achieved when the Pd/Cu metal ratio was 1:0.6 and on an Fe3O4 support. To explain the details of the synergistic effect according to the metal composition, authors investigated the electronic properties of the catalytic surface of PdxCuy on Fe3O4 NPs through the d. functional theory (DFT). DFT calculation and kinetic studies successfully delineated the catalytic activities of N-methylation depending on varying Pd/Cu ratios. Highly efficient monomethylation of a wide range of aromatic amines was possible using the optimally chosen Pd1Cu0.6 catalyst. Furthermore, the catalyst could be recycled and reused owing to the magnetic nature of the Fe3O4 support.

Lin, Weiwei published the artcileSelective N-Methylation of N-Methylaniline with CO2 and H2 over TiO2-Supported PdZn Catalyst, Related Products of isoquinoline, the main research area is methylation methylaniline carbon dioxide titania supported palladium zinc catalyst.

A series of Pd-ZnO/TiO2, Pd/TiO2, and Pd/ZnO catalysts were synthesized and investigated for N-methylation of N-methylaniline (MA) to N,N-dimethylaniline (DMA) with CO2 and H2. A high performance was observed with a Pd-ZnO/TiO2 catalyst, with 99.9% DMA selectivity at 94% MA conversion. By contrast, both Pd/TiO2 and Pd/ZnO were less active and/or selective. The catalytic performance of Pd-ZnO/TiO2 largely depended on reduction temperature and ZnO loading. The rates for MA conversion (rateMA) and DMA production (rateDMA) increased linearly with the amount of PdZn alloy formed. The reaction was likely to take place via intermediates of N-methylformanilide (MFA) and formate. Formate was produced through the reduction of CO2 with H2 as confirmed by in situ diffuse reflectance Fourier transform IR spectroscopy and then added to MA producing MFA, and finally, MFA was subsequently adsorbed and hydrogenated to DMA. All these steps were promoted by the PdZn alloy. The hydrogenation of MFA to DMA was much faster than the N-methylation of MA to MFA; DMA was stable, so the selectivity to DMA was almost 100% over the Pd-ZnO/TiO2 catalyst.

Electrocarboxylation of organic halides is one of the most investigated electrochem. approaches for converting thermodynamically inert carbon dioxide (CO2) into value-added carboxylic acids. By converting organic halides into their sulfone derivatives ArC(R)(R1)S(O)2C6H5 [Ar = Ph, thiophen-3-yl, 4-(tetramethyl-1,3,2-dioxaborolan-2-yl)benzen-1-yl, etc.; R = H, Me, Ph, D, but-2-yn-1-yl, etc.; R1 = H, Me, D, 2-methylprop-2-en-1-yl, etc.; RR1 = -(CH2)5-, -CH2CH=CHCH2-], a highly efficient electrochem. desulfonylative carboxylation protocol have been developed. Such a strategy takes advantage of CO2 as the abundant C1 building block for the facile preparation of multifunctionalized carboxylic acids ArC(R)(R1)C(O)OH, including the nonsteroidal anti-inflammatory drug ibuprofen, under mild reaction conditions.

Perry, Mitchell R. published the artcileMono, bis, and tris(phosphoramidate) titanium complexes: synthesis, structure, and reactivity investigations, Recommanded Product: 4-Methoxy-N-methylaniline, the main research area is mono bis phosphoramidate titanium preparation crystal mol structure reactivity; hydroamination catalyst mono bis phosphoramidate titanium complex preparation.

A series of variously substituted phosphoramidate titanium complexes bearing dimethylamido ligands are reported. Aryl-substituted ligands impart crystallinity to the systems and allow for the elucidation of the mol. structures via x-ray crystallog. Higher-substituted complexes, including a tris(phosphoramidate)mono(dimethylamido) complex, were isolated and characterized in the solid state, as well as in solution using variable temperature 1H and 31P NMR spectroscopy. The steric bulk possessed by this ligand system, relative to amidate and ureate ligands, has allowed access to a mono(phosphoramidate)tris(dimethylamido) complex. The first solid-state-mol. structure of a mono-ligated 1,3-N,O chelated complex of titanium is reported and compared to the resp. bis- and tris-analogs. These complexes were screened for hydroaminoalkylation activity between secondary amines and terminal alkenes and the intramol. hydroamination of a terminal aminoalkene. Mono(phosphoramidate)tris(dimethylamido) complexes were screened in situ and more active than their resp. bis(N,O)-chelated analogs. The elucidation of these complexes allows for a direct comparison to other N,O-chelates of early transition metals, particularly in their hydroaminoalkylation and hydroamination reactivity.
