A simple copper catalyzed “”one-pot”” process has been developed for synthesis of polysubstituted imidazoles via direct oxidative N-α-C(sp3)-H functionalization of arylmethylamines. The readily available arylmethylamines as substrates have afforded tetrasubstituted imidazoles products up to 94% yields under mild and environmentally benign conditions. The explored substrates scope with 1,2-diketones and α-hydroxyketones have shown great utility for synthesis of tetrasubstituted imidazoles.

Hao, Huimin; Shi, Ji-Long; Xu, Hui; Li, Xia; Lang, Xianjun published the artcile< N-hydroxyphthalimide-TiO2 complex visible light photocatalysis>, COA of Formula: C7H8BrN, the main research area is hydroxyphthalimide titania visible light photocatalysis.

TiO2 is the most established semiconductor photocatalyst. The prominence of TiO2 is becoming increasingly obvious because its interfacial redox reactions have implication on a wide range processes such as energy conversion and environmental remediation. Herein, we exploited the surface complex created by the interaction between organic mols. with binding sites and accommodating surface of TiO2 for visible light-driven selective aerobic oxidation reactions. A novel surface complex formed between N-hydroxyphthalimide (NHPI) and TiO2 was discovered. The NHPI-TiO2 complex turned out to be an outstanding visible light photocatalyst and was successfully used in the selective oxidation of amines into imines with atm. O2 under blue LED irradiation The stability of the NHPI-TiO2 complex was preserved by 3 mol.% of (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) acting as a cooperative catalyst. Moreover, selectivities for the imine products were also promoted by TEMPO. Superoxide anion radical (O·2-) were evidenced to be the primary reactive oxygen species (ROS) to execute the oxidative conversions. This work suggests that TiO2 surface complexes can be robust photocatalysts for visible light-driven selective aerobic reactions, provided that an appropriate cooperative redox catalyst exists to channel the photocatalytic electron transfer.

A series of scarce N-alkyl-2,5-unsubstituted/monosubstituted fulleropyrrolidines were synthesized in moderate to excellent yields by the simple one-step thermal reaction of [60]fullerene with primary/secondary amines in the presence of paraformaldehyde without the addition of valuable metal salts. Intriguingly, the reaction with primary amines unexpectedly afforded N-alkyl-2,5-unsubstituted fulleropyrrolidines instead of the anticipated 2,5-monosubstituted fulleropyrrolidines. A plausible reaction pathway is proposed to elucidate the above-mentioned reaction process based on the exptl. results.

Bai, Peng; Tong, Xinli; Wan, Jun; Gao, Yiqi; Xue, Song published the artcile< Flower-like Bi2O2CO3-mediated selective oxidative coupling processes of amines under visible light irradiation>, Recommanded Product: 4-Bromobenzylamine, the main research area is bismuth oxycarbonate amine oxidation photocatalyst.

The photocatalytic selective transformation of amines is a green and cost-effective technol. to obtain value-added products in chem. industry. In this work, a series of bismuth-based photocatalysts including Bi2MoO6, Bi2WO6, Bi5O7Cl, Bi5O7Br, Bi5O7I, BiPO4, BiVO4, Bi2O3 and various morphol. Bi2O2CO3 (flower-like, sponge-like, plate-like and spherical) were synthesized and employed in the aerobic oxidative coupling of benzylamine. It is found that flower-like Bi2O2CO3 exhibited the highest photocatalytic activity, in which a 100% conversion of benzylamine with 99.0% selectivity of N-benzylidenebenzylamine was obtained at room temperature Moreover, the photocatalytic oxidative coupling processes of various aromatic and aliphatic amines were further investigated, and excellent yields and selectivities of corresponding products are attained. Then, based on characterization results (XRD, SEM, BET and XPS, etc.) of catalyst, high photocatalytic activity of flower-like Bi2O2CO3 is attributed to thin nanopetals, low band gap, the morphol. and large sp. surface area. Finally, a possible reaction mechanism is proposed for the photocatalytic oxidative coupling of benzyl amine.

Xiang, Ming; Xu, Zhihua; Wu, Qianhui; Wang, Yanchen; Yan, Zhaoxiong published the artcile< Selective electrooxidation of primary amines over a Ni/Co metal-organic framework derived electrode enabling effective hydrogen production in the membrane-free electrolyzer>, Reference of 3959-07-7, the main research area is metal organic framework hydrogen production electrooxidation.

The overall water electrolysis always needs an ion-conductive membrane to sep. the generated hydrogen and oxygen from the corresponding cathode and anode, which improves the manufacturing cost of the electrolyzer. The substitution of thermodynamically more favorable organic oxidation reactions for oxygen evolution reaction avoids the requirement of the membrane, accompanied by the generation of value-added products at the anode. Herein, with the help of the bimetallic Ni/Co metal-organic framework derivative (t-Ni/Co MOF) as the anodic electrocatalyst, we develop an oxidant-free condition for the selective conversion of primary amines into nitriles. Specifically, aromatic and aliphatic nitriles can be conveniently obtained with good yields and faradaic efficiencies over the t-Ni/Co MOF electrode when coupling with the hydrogen evolution reaction. Notably, benzylamine can be oxidized into benzonitrile even at an ultralow potential of 1.30 V vs. reversible hydrogen electrode (RHE) over the t-Ni/Co MOF electrode, which is lower than that of the reported Ni-based monometallic electrocatalysts for benzylamine elecrooxidn. Control experiments suggest that the reversible electron transfer process of Co2+ ↔ Co3+ at a relatively low potential contributes to the formation of higher valence Ni species, which accelerates the kinetics of the primary amine oxidation, simultaneously reducing power consumption for hydrogen production

Gong, Weitao; Deng, Xiaorong; Dong, Kaixun; Liu, Lu; Ning, Guiling published the artcile< A boranil-based conjugated microporous polymer for efficient visible-light-driven heterogeneous photocatalysis>, Recommanded Product: 4-Bromobenzylamine, the main research area is boranil based conjugated polymer visible light driven heterogeneous photocatalysis.

The incorporation of pure organic dyes into the backbone of conjugated microporous polymers (CMPs) opens a new avenue for facile construction of metal-free heterogeneous photocatalysts with tailor-made properties. Herein, we presented the design and synthesis of a new CMP based on a boranil dye which was exploited as an efficient heterogeneous photocatalyst. It exhibited superior photocatalytic performance toward aerobic oxidation of amines and sulfides compared with that of the boranil-free counterpart and featured wide visible-light absorption, a narrow optical bandgap, and more planar π-conjugation due to boron complexation. The present study establishes boranil dyes as efficient building blocks for fabricating new photocatalysts.
