sigma-Bond nucleophiles and molecular oxygen transform aryl diazonium salts into aryl radicals. Experimental and computational studies show that Hantzsch esters transfer hydride to aryl diazonium species, and that oxygen initiates radical fragmentation of the diazene intermediate to produce aryl radicals. The operational simplicity of this addition-fragmentation process for the generation of aryl radicals, by a polar-radical crossover mechanism, has been illustrated in a variety of bond-forming reactions.

The efficient preparation of nitrile-containing building blocks is of interest due to their utility as synthetic intermediates and their prevalence in pharmaceuticals. As a result, significant efforts have been made to develop methods to access these motifs which rely on safer and non-toxic sources of CN. Herein, we report that 2-methyl-2-phenylpropanenitrile is an efficient, non-toxic, electrophilic CN source for the synthesis of nitrile-bearing quaternary centers by a thermodynamic transnitrilation and anion-relay strategy. This one-pot process leads to nitrile products resulting from the gem-difunctionalization of alkyl lithium reagents.

The crystal structures of seven alpha-aryl-alpha-hydroxyphosphonates synthesized by the Pudovik reaction of substituted benzaldehydes and dialkyl phosphites, namely dimethyl [(hydroxy)(phenyl)methyl] phosphonate, C9H13O4P, dimethyl [(3,4-dimethoxyphenyl)(hydroxy)methyl]phosphonate, C11H17O6P, dimethyl (1-hydroxy-1-phenylethyl) phosphonate, C10H15O4P, dimethyl [1-hydroxy-1-(4-nitrophenyl)ethyl]phosphonate, C10H14NO6P, dibenzyl [hydroxy(2-nitrophenyl)methyl]phosphonate, C21H20NO6P, dibenzyl [(3-chlorophenyl)(hydroxy)methyl]phosphonate, C21H20ClO4P, and dibenzyl [hydroxy(4-methylphenyl)methyl]phosphonate, C22H23O4P, were studied to gain a better understanding of the organization in this type of molecule in the solid state. The crystals obtained for this series of compounds show a balance between C-OH center dot center dot center dot O-P chain-linked packing and the dimeric types of hydrogen-bond bridges of intermolecular pairs of such functions. The description is based on primary graph-set descriptors. Using graph-set descriptors one level deeper (i.e. secondary graph sets of the C-H center dot center dot center dot O type) revealed a similarity in the graph-set descriptors, suggesting a fine interplay of substituent- and shape-dependent effects on strong-weak interactions. It seems that the formation of chains or dimers is governed not only by the presence of a tertiary C alpha atom, but also by the nature and crowding of the ortho substituents of the alpha-aryl group.

Nitro-reduction of aromatic nitro compounds into anilines has vast opportunities in synthetic chemistry. The catalytic systems used earlier operated under harsh conditions, which was very expensive to achieve end products. Visible light has advantages over the catalytic system due to the easy availability, low cost, and abundance. The present methodology describes the efficient reduction of a variety of aromatic nitro compounds into the corresponding anilines using a Z-scheme Fe2O3/BiVO4 photocatalyst under visible light illuminance. The photocatalyst demonstrated excellent activity up to 99% conversion of the nitrobenzene into aniline and for a series of nitroarenes as well at room temperature and atmospheric pressure visible light irradiation. The catalytic system has the advantage due to no leaching in the recycling experiments and high stability up to six cycles. The use of low-cost transition and p-block metal enhances the applicability of the catalytic system for aromatic nitro compounds reduction into the corresponding amines.

Modification of active metals with metal oxide modifiers has attracted considerable attention in heterogeneous catalysis due to their synergistic effect. However, a controllable synthesis of highly reactive and stable metal-metal oxide hybrid nanocatalysts is difficult. To solve this problem, presynthesized IrM (M = Fe, Co, and Ni) bimetallic nanoparticles were initially confined in the mesopores of SBA-15 and were then in situ transformed to Ir-MOx hybrids. The obtained Ir-MOx/SBA-15 nanocatalysts show superior activity and selectivity in the hydrogenation of substituted nitroaromatics to corresponding aromatic amines compared to Ir/SBA-15. Among these Ir-based catalysts, Ir-FeOx/SBA-15 exhibits the highest activity and selectivity and has a wider substrate scope due to the interaction between Ir and FeOx. Therefore, our research provides a way to design reactive and stable hydrogenation catalysts.

N-Aryl acetamides synthesis from the corresponding nitro compounds via a reductive N-acetylation was achieved over Pd supported on Sn modified Al2O3 catalyst using H-2, acetic anhydride as acetylating agent in aqueous media at ambient temperature. The pyridine-IR data demonstrated a majority of Lewis acid sites compared to Bronsted acid sites on the catalyst surface. Pyridine-IR and CO pulse chemisorption results emphasized a combination of surface palladium in conjunction with Lewis acid sites were responsible for the high activity of 2wt%Pd/5wt%Sn-Al2O3 over 2wt%Pd/Al2O3 catalyst with consistent activity and selectivity for four recycles. The bulk and surface properties of the catalysts were characterized by BET-SA, XRD, XPS, TPD of NH3, H-2-TPR, CO pulse chemisorption, TEM and the promotional effect of surface Lewis acid sites are rationalized by in situ pyridine adsorbed DRIFT spectroscopy.

Aim and Objective: Nowadays, the design, synthesis and application of magnetically nanocomposite systems have attracted the attention of numerous scientists. The huge surface area and magnetic characteristic of nanoparticles as well as the inherent potentiality of the used metal species, makes them susceptible to have different reactivity in chemical reactions. In this context, we therefore encouraged to prepare a new design of magnetic nanocatalysts as CuFe2O4@SiO2@AAPTMS@Ni(II) and CuFe2O4@SiO2@AAPTMS@Cu(II) followed by monitoring of their catalytic activities towards reduction of nitroarenes with NaBH4. Materials and Methods: Magnetically nanoparticles of CuFe2O4@SiO2@AAPTMS@Ni(II) and CuFe2O4@SiO2@AAPTMS@Cu(II) were prepared through a four-step procedure: i) preparation of CuFe2O4 MNPs, ii) coating of CuFe2O4 nucleus by silica-layer using tetraethyl orthosilicate (TEOS), iii) layering of CuFe2O4@SiO2 MNPs with [3-(2-aminoethylamino)propyl] trimethoxysilane (AAPTMS), and iv) the complexation of CuFe2O4@SiO2@AAPTMS MNPs with an aqueous solution of Ni(OAc)(2)center dot 4H(2)O or Cu(OAc)(2)center dot H2O. Results: The catalytic activity of CuFe2O4@SiO2@AAPTMS@AAPTMS@Ni(II) and the Cu(II)-analogue towards reduction of nitroarenes with NaBH4 was studied. The examinations resulted that using a molar ratio of 1:2 for ArNO2 and NaBH4 in the presence of 20 mg of nanocomposites in H2O under reflux conditions reduces various aromatic nitro compounds to arylamines in high yields. Conclusion: The immobilization of Ni(II) and Cu(II) species on silica-layered CuFe2O4 was investigated. Magnetically nanoparticles of CuFe2O4@SiO2@AAPTMS@Ni(II) and the Cu(II)-analogue showed the perfect catalytic activity towards reduction of nitroarenes with NaBH4, in H2O. All reactions were carried out within 2-15 min to afford aniline products in high yields.

Reductive catalysis with earth-abundant metals is currently of increasing importance and shows potential in replacing precious metal catalysis. In this work, we revealed catalytic hydroboration and hydrosilylation of ketones and aldehydes achieved by a structurally defined manganese(ii) coordination polymer (CP) as a precatalyst under mild conditions. The manganese-catalysed methodology can be applied to a range of functionalized aldehydes and ketones with turnover numbers (TON) of up to 990. Preliminary results on the regioselective catalytic hydrofunctionalization of styrenes by the Mn-CP catalyst are also presented.

In the present work, an efficient regioselective synthesis of 1,3,4-tri- and 1,3,4,5-tetrasubstituted pyrazoles via a methanesulfonic acid (MSA)-catalyzed reaction of hydrazones with enaminones or enamines is reported. Mechanistically, the formation of the title compounds involves the [2+3] cycloaddition of hydrazones with enaminones or enamines followed by aromatization with acid and oxygen. This convenient method under mild conditions with various hydrazones, enaminones, and enamines was well-tolerated to afford products in good to excellent yields. Compared with the literature methods, this strategy has advantages such as materials that are available economically, metal-free catalysis, excellent regioselectivity, and high efficiency.
