Wen, Daheng; Zheng, Qingshu; Wang, Chaoyu; Tu, Tao published the artcile< Rare-Earth-Catalyzed Transsulfinamidation of Sulfinamides with Amines>, Product Details of C7H8BrN, the main research area is rare earth catalyzed transsulfinamidation sulfinamide amine; secondary tertiary sulfinamide preparation.

A rare-earth-catalyzed transsulfinamidation of primary sulfinamides with alkyl, aryl, and heterocyclic amines for the synthesis of diverse secondary and tertiary sulfinamides has been realized. Unlike transition metal-catalyzed cross-coupling approaches restricted to non-com. available disubstituted O-benzoyl hydroxylamines, this newly developed protocol is suitable for diverse readily available primary and secondary amines without any modifications. Excellent catalytic activity and selectivity are achieved with Eu(OTf)3 under mild reaction conditions, which extends the applicability of rare-earth catalysis.

A sustainable advanced synthetic method were developed based on redox cyclization for the synthesis of 2-arylbenzothiazoles in good to excellent yields from readily available nitrobenzenes, benzylamines and elemental sulfur without the use of transition-metal catalysts. This method was remarkable: nitro group reduction, a benzylamine redox reaction, sulfuration, condensation and cyclization, all proceeded in a single step to generate a heterocycle. It was also highly atom-economical and does not require any external oxidizing or reducing agents.

Nishitani, Shohei; Sekiya, Ryo; Matsumoto, Ikuya; Haino, Takeharu published the artcile< Blueish-white-light-emitting Nanographenes Developed by Pd-catalyzed Suzuki-Miyaura Cross Coupling Reactions>, Product Details of C7H8BrN, the main research area is lead catalyst cross coupling reaction light emitting nanographene.

Top-down methods produce nanographenes with many carboxy groups on their edges. These functional groups can be utilized for developing multichromophoric systems. As proof of concept, pyrene is installed on the edges by Pd-catalyzed cross-coupling reactions. The lack of monomer emissions from the functionalized nanographenes indicates that the neighboring chromophores are sufficiently distant to form the excimer. The pyrene-installed nanographene emits bluish-white-light. Its lipophilic nature allows fabricating a nanographene-dispersed polymethyl methacrylate film emitting visible light.

Zhang, Kaiyue; Lu, Guilong; Chu, Feng; Huang, Xiubing published the artcile< Au/TiO2 nanobelts: thermal enhancement vs. plasmon enhancement for visible-light-driven photocatalytic selective oxidation of amines into imines>, Recommanded Product: 4-Bromobenzylamine, the main research area is mixed phase titanium dioxide nanobelt preparation; Au loaded titanium dioxide preparation; imine selective preparation; amine oxidation titanium dioxide nanocatalyst.

Herein, photocatalytic selective aerobic oxidation of amines to imines RCH2N=CHR1 [R = R1 = Ph, 2-BrC6H4, 3-pyridyl, etc.] was investigated under visible light irradiation over heterostructured TiO2(B)/anatase and Au/TiO2 nanobelts at specific temperatures (20-60°C). The surface amine substrate complexed on TiO2 could broaden the visible-light absorption region via the ligand-to-metal charge transfer (LMCT) effect. Interestingly, the pristine TiO2 achieved the best photocatalytic performance (>99% benzylamine conversion and >99% N-benzylidenebenzylamine selectivity) at 60°C after 12 h irradiation while the Au nanoparticles (NPs) were observed to improve the activity of TiO2 only in a low temperature range (<40°C). Moreover, excessive Au NPs loaded on TiO2 could inhibited the amine conversion and reduced the imine selectivity in the whole temperature range of 20-60°C, which was attributed to the decreased oxygen vacancies and poor amine adsorption ability on the surface of Au/TiO2.

Here, we report a highly efficient cooperative photocatalytic system for the selective oxidation of amines with air. The visible light-assisted adsorption of amines gives rise to a visible light complex on TiO2 that can be self-repaired to safeguard smart photocatalysis. Smart TiO2 photocatalysis works cooperatively with TEMPO catalysis that can perform the visible light-mediated selective oxidation of amines in a swift and recyclable manner. This discovery provides an alternative for addressing environmental challenges by reducing pollutants at the source for oxidative chem. reactions. (c) 2020 American Institute of Physics.

A series of novel ortho-terphenylene viologen derivatives (o-TPV2+) with through-space conjugation (TSC) via the combination of ortho-terphenylene skeletons with viologen structure is reported. Their optoelectronic properties can be adjusted by N-arylation or N-alkylation reactions. Compared with other viologen derivatives, o-TPV2+ not only exhibits strong photoluminescence, but also retards the charge recombination process and stabilizes diradicals state without forming a quinoid structure due to the special TSC effect. Based on their special redox characteristics, o-TPV2+ were applied to the photocatalytic oxidative coupling of benzylamine with 96% yield. In addition, pTA-o-TPV2+ (tethered with p-toluic acid) modified g-C3N4 was used for visible-light-driven hydrogen production for the first time, exceeding 15 times the rate over unmodified g-C3N4.
