The potential of using chiral bicyclic NHC ligands that exhibit modularity was investigated in the Cu-catalyzed asymmetric borylation reaction of alpha,beta-unsaturated esters. After screening for ligands and optimization of the reaction conditions, the corresponding products were afforded with good enantioselectivities (up to 85% ee).

Established electrodecarboxylative etherification protocols are based on Hofer-Moest-type reaction pathways. An oxidative decarboxylation gives rise to radicals, which are further oxidised to carbocations. This is possible only for benzylic or otherwise stabilised substrates. Here, we report the electrodecarboxylative radical-radical coupling of lithium alkylcarboxylates with 1-hydroxybenzotriazole at platinum electrodes in methanol/pyridine to afford alkyl benzotriazole ethers. The substrate scope of this electrochemical radical coupling extends to primary and secondary alkylcarboxylates. The benzotriazole products easily undergo reductive cleavage to the alcohols. They can also serve as synthetic hubs to access a wide variety of functional groups. This reaction prototype demonstrates that electrodecarboxylative C-O bond formation can be taken beyond the intrinsic substrate limitations of Hofer-Moest mechanisms.

The condensation of MeP(SiMe3)(2) with a series of 5-substituted isophthaloyl chlorides (5-R’C6H3-2,6-{C(O)Cl}(2)) affords the diphosphametacyclophanes m-{-C(O)-C6H3-5-R’-(C(O)PMe)}(2) (R’ = I, Me, tBu, Ph, and p-NCC6H4); the analogues m-{-C(O)-C5H3N-(C(O)PMe)}(2) and m-{-C(O)-C6H4-(C(O)PPh)}(2) are similarly obtained in preference to higher oligomers, in contrast to precedent reports. The cyclophanes all adopt butterfly-like conformations in the solid state with the P-organyl substituents adopting mutually exo arrangements. Structural and computational data suggest the nature of the 5-R substituent is key in directing the inter-ring angle and the extent of LUMO stabilization about the diketophophanyl scaffold. The latter is substantiated by UV/vis spectroscopy and cyclic voltammetry, which demonstrate these cyclophanes to be appreciably comparable to the diketophosphanyl systems commonly explored in the context of organic electronic materials; intriguingly, the distinct dikeophosphanyl moieties within the macrocycles appear effectively insulated by the macrocycle geometry, rather than acting as a through-conjugate.

In order to discover more potent antifungal, a series of 2-aryl-3,4-dihydroisoquinolin-2-iums were reasonable designed and productive synthesized by introducing benzoic acid and phenol pharmacophores into the 2-position of isoquinoline. Their structures were identified by NMR and HRMS. The preliminary in vitro antifungal results showed that most of the title compounds exhibited moderate to significant inhibitory activities against various phytopathogenic fungi at 50 mu g.mL(-1), and were equal to controls (chlorothalonil, carbendazim). The concentration of 50% inhibition rate (EC50]) of 2-(3-ethoxycarbonyl-phenyl)-3,4-dihydroisoquinolin-2-ium (4j) against R. solani was 3.8495 mu g.mL(-1), which was significantly superior to chlorothalonil (4.6328 mu g.mL(-1)). All the EC50 values of 5 compounds (7.4583 similar to 15.4495 mu g.mL(-1)) against R. cerealis were better than chlorothalonil (16.0137 mu g.mL(-1)), and 2-(4-methoxycarbonylphenyl)-3,4-dihydroisoquinolin-2-ium (4f) is the best one. The present results provide valuable information for development of plant-based antifungal agents.

A mild and efficient protocol for the intramolecular aromatic C-H oxygenation of 2-biphenylcarboxylic acids has been achieved via iron photocatalysis. The 2-biphenylcarboxylic acids with a diverse array of substituents at both phenyl rings could furnish the oxygenation products in good to excellent yields. We speculate that the aryl carboxylate-iron(III) complexes should generate the aroyloxy radicals and iron(II) upon visible light irradiation.

Catalytic conversion of lignin to versatile aromatic compounds is attracting increasing attention. However, it is highly desirable but challenging to produce a specific chemical with high yield through lignin depolymerization in a one-pot process because of the complex structure of the lignin molecule (mainly composed of H, G, and S units). In this study, a series of metal-based deep eutectic solvents (M-DESs) were prepared and used for the catalytic tailoring of lignin H units to produce value-added methyl p-hydroxycinnamate (MPC). In particular, M-DES ChCl[FeCl3](2) showed excellent catalytic performance for the selective production of MPC as the sole product with high yield and selectivity (105.8 mg g(-1) and 74.1%, respectively). Extensive characterizations using 2D HSQC NMR, C-13 NMR, and GPC demonstrated that MPC was obtained from the selective tailoring of p-coumaric acid (pCA) units via the cleavage of ester bonds in lignin. Furthermore, M-DES ChCl[FeCl3](2) also exhibited efficiency to other herbaceous lignins, and showed excellent recyclability. Therefore, this work provides an effective strategy for the valorization of lignin.

A simple and an efficient approach for in situ preparation of palladium nanoparticles (Pd NPs) in ionic liquid crystal (ILC) microemulsion is described. Microemulsion was formed by using a ternary mixture of triton X-100/ILC/water (in the ratio of 1.4:0.1:8.5). Three such microemulsions-1, 2 and 3 were formed by using three different ILCs namely ammonium ILC containing a cholesterol core (ILC-1), imidazolium ILC bearing a cholesterol core (ILC-2) and imidazolium ILC containing a biphenyl core (ILC-3), respectively. The Pd NPs were characterised using UV-vis spectroscopy, transmission electron microscopy and X-ray diffraction studies. Among the three, microemulsion-2 which was prepared using ILC-2 yielded stable NPs with an average particle size of similar to 20 nm. The NPs prepared in all three emulsions were examined as catalyst for Heck reaction. The catalytic efficiency was analysed for four cross-coupling reactions involving iodobenzene with different substituted alkenes namely methyl acrylate, ethyl acrylate, butyl acrylate and styrene. The coupling reactions were completed in a shorter period with good yields. Further, the recyclability test of Pd NPs revealed that the particles showed good activity until third catalytic cycle. The Pd NPs prepared in microemulsion-2 showed better activity compared to those prepared in microemulsions-1 and -3. (C) 2020 Elsevier B.V. All rights reserved.

The first catalyst for the alkoxycarbonylation of gem-difluoroalkenes is described. This novel catalytic transformation proceeds in the presence of Pd(acac)(2)/1,2-bis((di-tert-butylphosphan-yl)methyl)benzene (btbpx) (L4) and allows for an efficient and straightforward access to a range of difluoromethylated esters in high yields and regioselectivities. The synthetic utility of the protocol is showcased in the practical synthesis of a Cyclandelate analogue using this methodology as the key step.

Herein, two novel isostructural metal-organic frameworks (MOFs) M-URJC-4 (M = Co, Ni; URJC = Universidad Rey Juan Carlos) with open metal sites, permanent microposity, and large surface areas and pore volumes have been developed. These novel MOFs, with polyhedral morphology, crystallize in the monoclinic P2(1)/c space group, exhibiting a three-dimensional structure with microporous channels along the c axis. Initially, they were fully characterized and tested in hydrogen (H-2) adsorption at different conditions of temperature and pressure. The physisorption capacities of both materials surpassed the gravimetric H-2 uptake shown by most MOF materials under the same conditions. On the basis of the outstanding adsorption properties, the Ni-URJC-4 material was used as a catalyst in a one-pot reductive amination reaction using various carbonyl compounds and primary amines. A possible chemical pathway to obtain secondary amines was proposed via imine formation, and remarkable performances were accomplished. This work evidences the dual ability of M-URJC-4 materials to be used as a H-2 adsorbent and a catalyst in reductive amination reactions, activating molecular H-2 at low pressures for the reduction of C=N double bonds and providing reference structural features for the design of new versatile heterogeneous materials for industrial application.
