A versatile metal- and base-free direct reductive amination of aldehydes with amines using formic acid as a reductant under the catalysis of inexpensive BF3·Et2O has been developed. A wide range of primary and secondary amines and diversely substituted aldehydes are compatible with this transformation, allowing facile access to various secondary and tertiary amines in high yields with wide functional group tolerance. Moreover, the method is convenient for the late-stage functionalization of bioactive compounds and preparation of commercialized drug mols. and biol. relevant N-heterocycles. The procedure has the advantages of simple operation and workup and easy scale-up, and does not require dry conditions, an inert atm. or a water scavenger. Mechanistic studies reveal the involvement of imine activation by BF3 and hydride transfer from formic acid.

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.

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.

Fan, Xiuwei published the artcilePhotocatalytic C-C Bond Activation of Oxime Ester for Acyl Radical Generation and Application, HPLC of Formula: 5961-59-1, the main research area is oxindole cyclobutane preparation photocatalytic carbon bond activation oxime ester.

A unified strategy to generate acyl radical from oxime ester via selective C-C bond activation is reported. Under visible-light irradiation, single-electron transfer from fac-Ir(ppy)3 to related oxime takes place followed by a fast β-fragment of C-C bond to yield aryl and aliphatic acyl radicals, subsequently captured by diverse Michael acceptors. More interestingly, the single-electron transfer enables coupling with energy transfer of the excited fac-Ir(ppy)3 via enone intermediate formed in situ for cyclobutane formation.

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.
