This work focused on the synthesis of 3D Pd-based nanocomposites which were tested in Heck coupling reactions and for the hydrogenation of nitroarenes. This was achieved by fabrication of graphene oxide/nitrogen-doped carbon nanotubes (G/N-CNTs) by mechanical grinding of 2D graphene oxide (GO) and 1D oxygen-treated nitrogen-doped CNTs (N-CNTs-OT) in a 3:1 ratio, respectively. The fabrication of G/N-CNTs is to overcome the habitual aggregation and restacking of graphene sheets. Palladium nanoparticles (Pd NPs) were deposited on the 3D G/N-CNTs nanocomposites via metal organic chemical vapour deposition method. The 3D Pd-based nanocomposites were characterized by TEM, SEM, HRTEM, XRD, TGA, XPS, ICP-OES, elemental analysis, BET analysis and Raman spectroscopy. For the Heck coupling reactions, aryl halides, olefins and 3D Pd-based nanocomposites were mixed in a suitable solvent and the reaction carried under microwave irradiation.The chemoselective hydrogenation of nitroarenes was done with dry ethanol in a Paar reactor, purged with H-2 gas. These catalysts demonstrate excellent activity and selectivity in both reactions. The remarkable activity of the 3D Pd-based nanocomposites in Heck reactions and hydrogenation of nitroarenes may be attributed to the small particle size (3-10 nm) and a high degree of dispersion of Pd NPs. A comparative experiment was conducted with Pd/AC, Pd/CNTs, Pd/G/CNTs and Pd/rGO. Pd/G/N-CNTs-OT showed higher activity and selectivity than Pd/G/CNTs, Pd/G/N-CNTs, Pd/rGO and Pd/N-CNTs counterpart.

Useful alpha-boryl esters can be synthesized in one step from alpha,beta-unsaturated esters using just a simple to access NHC-BH3 (NHC = N-heterocyclic carbene) and catalytic I-2. The scope of this reductive alpha-borylation methodology is excellent and includes a range of alkyl, aryl substituted and cyclic and acyclic alpha,beta-unsaturated esters. Mechanistic studies involving reductive borylation of a cyclic alpha,beta-unsaturated ester with NHC-BD3/I-2 indicated that concerted hydroboration of the alkene moiety in the alpha,beta-unsaturated ester proceeds instead of a stepwise process involving initial 1,4-hydroboration; this is in contrast to the recently reported reductive alpha-silylation. The BH2(NHC) unit can be transformed into electrophilic BX2(NHC) moieties (X = halide) and the ester moiety can be reduced to the alcohol with the borane unit remaining intact to form b-boryl alcohols. The use of a chiral auxiliary, 8-phenylmenthyl ester, also enables effective stereo-control of the newly formed C-B bond. Combined two step ester reduction/borane oxidation forms diols, including excellent e. e. (97%) for the formation of S-3-phenylpropane-1,2-diol. This work represents a simple transition metal free route to form bench stable alpha-boryl esters from inexpensive starting materials.

In contrast to the plethora of large-bite-angle bisphosphine ligands available to transition-metal catalysis, the development of small-bite-angle bisphosphine ligands has suffered from the limited structural variations accessible on their single-atom-containing backbones. Herein, we report the design and applications of a discrete very small bite-angle bisphosphine ligand, namely, FMPhos. Featuring a fluorene-methylene unit appended on the single-carbon linker, the ligand harbors an unusually rigid backbone that presumably stabilizes its complexation with transition metals during catalysis. Compared with the known dppm ligand, it exhibited superior reactivity and regioselectivity in a number of alkene hydrofunctionalization reactions, catalyzed by iridium and rhodium.

Fluorine-containing organic molecules, particularly those that bear (sp(3))C-F bonds, are rapidly gaining prominence in modern chemical synthesis. Although extensive studies have been devoted to the preparation of secondary and tertiary fluorides, crucial shortcomings remain: for example, lengthy substrate synthesis, contrived installation of difficult-to-remove directing/activating units, excessive waste generation and/or limited functional group compatibility. Here, we show that readily accessible alpha-onofluoro carboxylic acids, which are conventionally difficult substrates for cross-coupling, undergo direct decarboxylative crosscoupling with sp(2-) and sp(3-)hybridized organohalides to afford a wide assortment of fluorinated products. Reactions are typically promoted by a combination of 1 mol % of an Ir-based photocatalyst and 2-15 mol % of a bipyridine-Ni complex, delivering products in up to 86% yield under blue LED light irradiation. Concise synthesis of key therapeutic candidates underscores utility, complementarity, and distinct advantages compared with existing methods. DFT calculations are used to rationalize the distinct reactivity of alpha-fluoro carboxylic acid substrates (vs nonfluorinated parent acids) under decarboxylation conditions.

The paper describes synthesis of a novel mesoporous and magnetically regenerated heterogeneous nanocatalyst with high catalytic activity. The synthesis strategy includes a one-step polycondensation reaction of melamine, formaldehyde and FeCl3 center dot 6H(2)O in a simple and sustainable manner and followed by immobilization of Pd(II) on it. Formation and properties of nanocomposite were characterized by different techniques; the results were illustrated good surface area and a well-defined mesopore structure. Also the palladium-catalyzed C-C bond formation between aryl halides and olefins was selected to survey the activity of the synthesized nanocatalyst. Central Composite Design (CCD) strategy was used to predict the optimum synthesis conditions and identify the remarkable and effective factors including temperature, period of the reaction and amount of catalyst. These results were also verified experimentally. In order to minimize systematic error, the experimental runs as a randomized fashion were accomplished.

Herein we report the first example of an on-water enantiospecific synthesis of alkyl bromides. This procedure allowed the conversion of secondary activated alkyl sulphides to benzylic alkyl bromides, which were obtained in 80-99% yields. The reaction carried out on enantio-pure sulphides provided the corresponding bromides in high yields and enantioselectivity (up to 92% ee; 94% es) at room temperature. The on-water conditions reduced significantly the reaction times compared to similar procedures run in organic media. The condition identified made use of no solvent, required no temperature control and produced a smooth organic phase easily separated for further synthetic use on a multigram-scale without the need for any organic extraction. Therefore, the present constitutes the most operationally simple and environmentally benign approach to a class of much sought organic intermediates.

A series of cinnamic monomers, which can be derived from naturally occurring phenylpropanoids, were radically copolymerized with vinyl monomers such as methyl acrylate (MA) and styrene (St). Although the monomer reactivity ratios were close to zero for all the cinnamic monomers, such as methyl cinnamate (CAMe), cinnamic acid (CA), N-isopropyl cinnamide (CNIPAm), cinnamaldehyde (CAld), and cinnamonitrile (CN), they were incorporated into the copolymers and significantly increased the glass transition temperatures despite the relatively low incorporation rates of up to 40 mol % due to their rigid 1,2-disubstituted structures. The regioselectivity of the radical copolymerization of CAMe was evaluated on the basis of the results of ruthenium-catalyzed atom transfer radical additions as model reactions. The obtained products suggest that the radicals of MA and St predominantly attack the vinyl carbon of the carbonyl side of CAMe and that the propagation of CAMe mainly occurs via the styrenic radical. The ruthenium-catalyzed living radical polymerization, nitroxide-mediated polymerization (NMP), and reversible addition-fragmentation chain transfer (RAFT) polymerization provided the copolymers with controlled molecular weights, narrow molecular weight distributions, and controlled comonomer compositions. The copolymers of N-isopropylacrylamide (NIPAM) and CNIPAm prepared via RAFT copolymerization showed thermoresponsivity with a lower critical solution temperature (LCST) that could be tuned by altering the comonomer incorporation and a higher LCST than the copolymers of NIPAM and St, which possessed similar molecular weights and similar NIPAM contents, due to the additional N-isopropylamide groups in the CNIPAm units compared to the St units.
