Highly efficient heterogeneous aerobic cross-dehydrogenative coupling via C-H functionalization of tertiary amines using a nanoporous gold skeleton catalyst

We report for the first time that zero-valent nanoporous gold (AuNPore) is a robust and green heterogeneous catalyst for alpha-C-H functionalization of various tertiary amines. AuNPore combines with molecular oxygen at 80 C or tert-butyl hydrogen peroxide at room temperature and catalyses the heterogeneous cross-dehydrogenative coupling (CDC) reaction efficiently to afford the corresponding C-C and C-heteroatom coupling products in good to excellent yields with excellent reusability.

Tuning the Ionicity of Stable Metal-Organic Frameworks through Ionic Linker Installation

The predictable topologies and designable structures of metal-organic frameworks (MOFs) are the most important advantages for this emerging crystalline material compared to traditional porous materials. However, pore-environment engineering in MOF materials is still a huge challenge when it comes to the growing requirements of expanded applications. A useful method for the regulation of pore-environments, linker installation, has been developed and applied to a series of microporous MOFs. Herein, employing PCN-700 and PCN-608 as platforms, ionic linker installation was successfully implemented in both microporous and mesoporous Zr-based MOFs to afford a series of ionic frameworks. Selective ionic dye capture results support the ionic nature of these MOFs. The mesopores in PCN-608 are able to survive after installation of the ionic linkers, which is useful for ion exchange and further catalysis. To illustrate this, Ru(bpy)32+, a commonly used photoactive cation, was encapsulated into the anionic mesoporous PCN-608-SBDC via ion exchange. Photocatalytic activity of Ru(bpy)3@PCN-608-SBDC was examined by aza-Henry reactions, which show good catalytic performance over three catalytic cycles.

Ruthenium-catalyzed alkylation of indoles with tertiary amines by oxidation of a sp3 CH bond and lewis acid catalysis

Ruthenium porphyrins (particularly [Ru(2,6-Cl2tpp)CO]; tpp = tetraphenylporphinato) and RuCl3 can act as oxidation and/or Lewis acid catalysts for direct C-3 alkylation of indoles, giving the desired products in high yields (up to 82% based on 60-95% substrate conversions). These ruthenium compounds catalyze oxidative coupling reactions of a wide variety of anilines and indoles bearing electron-withdrawing or electron-donating substituents with high regioselectivity when using tBuOOH as an oxidant, resulting in the alkylation of N-arylindoles to 3{[(N-aryl-N-alkyl)amino]methyl} indoles (yield: up to 82%, conversion: up to 95%) and the alkylation of N-alkyl or N-H indoles to 3-[p-(dialkylamino)benzyl]indoles (yield: up to 73%, conversion: up to 92%). A tentative reaction mechanism involving two pathways is proposed: an iminium ion intermediate may be generated by oxidation of an sp3 C-H bond of the alkylated aniline by an oxoruthenium species; this iminium ion could then either be trapped by an N-arylindole (pathway A) or converted to formaldehyde, allowing a subsequent three-component coupling reaction of the in situ generated formaldehyde with an N-alkylindole and an aniline in the presence of a Lewis acid catalyst (pathway B). The results of deuterium-labeling experiments are consistent with the alkylation of N-alkylindoles via pathway B. The relative reaction rates of [Ru(2,6-Cl 2tpp)CO] catalyzed oxidative coupling reactions of 4-X-substituted N,N-dimethylanilines with N-phenylindole (using tBuOOH as oxidant), determined through competition experiments, correlate linearly with the substituent constants o (R2=0.989), giving a rho value of -1.09. This rho value and the magnitudes of the intra- and intermolecular deuterium isotope effects (kH/kD) suggest that electron transfer most likely occurs during the initial stage of the oxidation of 4-X-substituted N,N-dimethylanilines. Ruthenium-catalyzed three-component reaction of N-alkyl N-H indoles, paraformaldehyde, and anilines gave 3-[p-(dialkylamino)benzyl] indoles in up to 82% yield (conversion: up to 95%).

Non-covalent molecular tweezer/guest complexation with Pt(II) Pt(II) metal-metal interactions: Toward intelligent photocatalytic materials

A new organoplatinum(II) molecular tweezer with a stimuli-responsive 2,20:60,200-terpyridine spacer has been synthesized, which undergoes ”U”- to ”W”-shaped conformational transition upon adding Zn2+ ions. The molecular tweezer receptor displays a high binding affinity toward the complementary guests, with the implementation of Pt(II)Pt(II) metal-metal interactions for the non-covalent tweezering systems. MMLCT absorbance simultaneously emerges in the visible-light region (470-620 nm), which can be sensitized by O2 and thereby utilized for photo-catalyzed reactions in organic and aqueous media. Moreover, temporally ”on-demand” photo-catalytic efficiency can be accomplished, via the successive addition of Zn(OTf)2 and a competitive ligand to the supramolecular tweezering photosensitizers. Hence, the current study opens up new avenues toward intelligent photocatalytic materials via elaborate supramolecular engineering.

A Cu-catalyzed [4+1] annulation of N-aryl-1,2,3,4-tetrahydroisoquinolines (N-aryl THIQs) with alpha-diazoketones has been established under oxidative conditions, leading to the construction of a series of indolo[2,1-a]isoquinolines with generally good yields.

Synthesis and properties of push-pull imidazole derivatives with application as photoredox catalysts

Two new push-pull molecules with imidazole-4,5-dicarbonitrile acceptor, thiophene and 2-methoxythiophene donors with potential use in photoredox catalysis were designed and prepared. The synthesis started from commercially available imidazole-4,5-dicarbonitrile and its bromination and N-methylation. Subsequent Suzuki-Miyaura cross-coupling with (5-methoxy)thiophene-derived boronic acids afforded target push-pull derivatives. Beside common analytical methods, the molecular structure of 5-methoxythiophen-2-yl derivative has also been verified by X-ray analysis. DSC analyses showed remarkable thermal stabilities of both target derivatives with Tm and TD values above 150 and 270 C, respectively. Fundamental properties and extent of the intramolecular charge-transfer were further studied by UV-VIS absorption spectra and DFT calculations. Fundamental photoredox properties of target imidazole derivatives were elucidated. Both push-pull molecules were preliminary tested as photoredox catalysts in cross-dehydrogenative coupling reaction between tetrahydroisoquinoline and nitromethane and the results were compared with those obtained by pyrazine-2,3-dicarbonitrile-derived catalyst.

Metal-organic framework composites with luminescent pincer platinum(II) complexes: 3MMLCT emission and photoinduced dehydrogenation catalysis

Pincer platinum(ii) complexes are well documented to exhibit weak intermolecular interactions in the solid state and 77 K glassy solutions, leading to emissive triplet metal-metal-to-ligand charge transfer (3MMLCT) excited states that often vanish in dilute solutions. In this work, metal-organic framework (MOF) materials are introduced to provide a “solid solution” environment for easy access to 3MMLCT excited states of pincer platinum(ii) complexes. Phosphorescent composites PtII@MOFs (1-4) with matrix-dependent monomers and oligomer emission properties were obtained. These PtII@MOFs are efficient catalysts for photoinduced dehydrogenation reactions.
