A tandem aerobic oxidation protocol has been developed for the facile synthesis of indole-3-carboxylates. Two readily available starting materials, anilines and benzylamines, were efficiently cross-coupled under the o-naphthoquinone-catalyzed aerobic oxidation conditions to the corresponding 2-arylmethyleneaminophenylacetates that in turn smoothly underwent the Cu(II)-catalyzed intramol. Mannich reaction. The resulting indoline derivatives were aerobically oxidized to indole-3-carboxylates, providing a ready access to indole derivatives from two simple amine derivatives

Liu, Shufang; Su, Qing; Qi, Wei; Luo, Kexin; Sun, Xiaoman; Ren, Hao; Wu, Qiaolin published the artcile< Highly hydrophilic covalent organic frameworks as efficient and reusable photocatalysts for oxidative coupling of amines in aqueous solution>, Recommanded Product: 4-Bromobenzylamine, the main research area is covalent organic framework catalyst preparation thermal stability; benzyl amine covalent organic framework catalyst photochem oxidative coupling; phenyl benzyl methanimine diastereoselective preparation.

Three hydrophilic two-dimensional (2D) COFs achieved by a polycondensation reaction of 2,5-dimethoxyterephthalohydrazide (DMTH), 1,3,5-triformylbenzene (TFB) and 2-hydroxy-1,3,5-benzene tricarbaldehyde (SOH) under solvothermal conditions was reported. The resulted COF materials, TFB-XX-DMTH (XX = 33, 50 and 66, corresponding to a molar ratio of TFB/SOH = 1 : 2, 1 : 1 and 2 : 1), were successfully constructed by a three-component in-situ assembly strategy and thus exhibited high crystallinity, large surface areas (up to 1808 m2 g-1) and good thermal and chem. stability. Moreover, benefiting from the enhanced charge separation efficiency and high hydrophilicity, the TFB-XX-DMTH materials were employed as photocatalysts for visible-light-driven oxidative coupling reactions of benzylamines in aqueous solution The photocatalytic performance with high conversion, selectivity and recyclability could be attributed to a combined result of efficient generation, migration and separation of photogenerated carriers in such a platform. This results provide insights into the structure-function correlation of COF photocatalysts and also highlight their potential in developing photofunctional COFs for sustainable organic transformations.

Zhang, Shishen; Chen, Kelong; Peng, Wen; Huang, Jianhua published the artcile< g-C3N4/Uio-66-NH2 nanocomposites with enhanced visible light photocatalytic activity for hydrogen evolution and oxidation of amines to imines>, Synthetic Route of 3959-07-7, the main research area is water splitting photocatalysis photooxidation amine imine nanocomposite MOF.

G-C3N4/Uio-66-NH2 (CNUIO) nanocomposites were prepared by growing an NH2-mediated zirconium-based metal-organic framework (Uio-66-NH2) in the presence of g-C3N4 nanotubes. CNUIO exhibited efficient photocatalytic performance in the oxidation of amines to imines and hydrogen production under visible light illumination. The optimal Uio-66-NH2 content in CNUIO was 16.7 wt% with a H2-generation rate of 152.2μmol h-1, which is about 1.7 and 39 times as high as those of g-C3N4 and Uio-66-NH2, resp. The optimal conversion rate of benzylamine was 58.9%, which is about 3.4 and 10.5 times as high as those of g-C3N4 and Uio-66-NH2, resp. The probable photocatalytic mechanism of the CNUIO composite was investigated. This work provides a new insight into the fact that g-C3N4/MOF photocatalysts have great potential application in hydrogen production and organic synthesis.

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 mild impregnation of graphene acid (GA) with Pd(OAc)2 yields Pd nanoparticles with a size that can be easily controlled by the amount of the Pd precursor, and with a sharp and tunable size distribution ranging from 1 nm up to 9 nm. The spectroscopic and microscopic characterization of the GA-Pd composites reveals a strong interaction between the metal and the carboxyl groups of the GA support, and suggests a nanoparticle growth mechanism entailing counterion metathesis followed by a GA promoted reduction The GA-Pd nanohybrids are highly active catalysts in the Suzuki-Miyaura cross coupling reaction under environmentally-friendly conditions. TOF values exceeding 30 000 h-1, high selectivity toward the coupling product and versatility for a large variety of substrates are reported. Given the large amount of carboxyl groups, the catalysts are exceptionally stable, and no appreciable metal leaching is observed during the reaction. Notably, at variance with conventional carbon and graphene supports, the GA supported Pd nanoparticles show a bifunctional activity and can yield biphenyl adducts upon oxidative homocoupling of arylboronic acids.
