Enhancing Chemo- And Stereoselectivity in C-H Bond Oxygenation with H2O2by Nonheme High-Spin Iron Catalysts- And Role of Lewis Acid and Multimetal Centers

Spin states of iron often direct the selectivity in oxidation catalysis by iron complexes using hydrogen peroxide (H2O2) on an oxidant. While low-spin iron(III) hydroperoxides display stereoselective C-H bond hydroxylation, the reactions are nonstereoselective with high-spin iron(II) catalysts. The catalytic studies with a series of high-spin iron(II) complexes of N4 ligands with H2O2 and Sc3+ reported here reveal that the Lewis acid promotes catalytic C-H bond hydroxylation with high chemo- and stereoselectivity. This reactivity pattern is observed with iron(II) complexes containing two cis-labile sites. The enhanced selectivity for C-H bond hydroxylation catalyzed by the high-spin iron(II) complexes in the presence of Sc3+ parallels that of the low-spin iron catalysts. Furthermore, the introduction of multimetal centers enhances the activity and selectivity of the iron catalyst. The study provides insights into the development of peroxide-dependent bioinspired catalysts for the selective oxygenation of C-H bonds without the restriction of using iron complexes of strong-field ligands.

Catalytic hydrogenation of aromatic rings catalyzed by Pd/NiO

A simple and efficient heterogeneous palladium catalyst was prepared for aromatic ring hydrogenation. The catalyst was prepared by a reduction-deposition method and exhibited high activity and selectivity for the hydrogenation of a variety of substituted aromatic compounds to the corresponding cyclohexane and cyclohexanol derivatives with up to 99% yields. The catalyst was characterized by BET, TEM, XRD, XPS and ICP. Meanwhile the reusability of the catalyst was investigated, and it can be reused for several runs without significant deactivation.

Synthesis of poly(decahydro-2-naphthyl methacrylate)s with different geometric structures and effects of side-group dynamics on polymer properties investigated by thermal and dynamic mechanical analyses and DFT calculations

We prepared the geometric isomers of decahydro-2-naphthols as the source materials for the synthesis of poly(decahydro-2-naphthyl methacrylate)s [poly(DNMA)-I, -II, -III, and -IV] including alicyclic ester groups with different geometric structures. The geometry and conformational dynamics of the decahydro-2-naphthyl moieties were investigated by NMR spectroscopy and DFT calculations. We synthesized each isomer of the methacrylic monomers, polymerized them, and investigated the optical, thermal, and mechanical properties of poly(DNMA)s with different isomer compositions. The Tg values of the poly(DNMA)s were in the following order: 139.3 C for poly(DNMA)-II 3/g, 1.489, and 42-44, respectively.

An iron catalyst for oxidation of alkyl C-H bonds showing enhanced selectivity for methylenic sites

Many are called but few are chosen: A nonheme iron complex catalyzes the oxidation of alkyl C-H bonds by using H2O2 as the oxidant, showing an enhanced selectivity for secondary over tertiary C-H bonds (see scheme). Copyright

Oxidative functional group transformations with hydrogen peroxide catalyzed by a divanadium-substituted phosphotungstate

A divanadium-substituted phosphotungstate TBA4[γ-PW 10O38V2(μ-OH)(μ-O)] (I, TBA = tetra-n-butylammonium) reacts with one equivalent H+ to form a bis-μ-hydroxo species [γ-PW10O38V 2(μ-OH)2]3- (I′) in organic media. The strong electrophilic oxidants such as [γ-PW10O 38V2(μ-OH)(μ-OOH)]3- (II) and [γ-PW10O38V2(μ-η2: η2-O2)]3- (III) are formed by the reaction of the bis-μ-hydroxo species with H2O2. In the presence of I and H+, H2O2-based oxidations such as (i) epoxidation of alkenes (17 examples including electron-deficient ones), (ii) hydroxylation of alkanes (11 examples), and (iii) oxidative bromination of alkenes, alkynes, and aromatics with Br- as a bromo source (12 examples including chlorination) chemo-, diastereo-, and regioselectively proceed to give the corresponding oxidized products in moderate to high yields with high efficiencies of H2O2 utilization.

Synthesis and Pseudomonas lipase inhibition study of stereoisomers of decahydro-2-naphthyl-N-n-butylcarbamate

(2S,4aR,8aS)-Cis,cis-, (2R,4aS,8aR)-cis,cis-, rac-cis,cis-, and rac-trans,cis-decahydro-2-naphthyl-N-n-butylcarbamates are synthesized from condensation of (2S,4aR,8aS)-cis,cis-, (2R,4aS,8aR)-cis,cis-, rac-cis,cis-, and rac-trans,cisdecahydro-2-naphthols, respectively, with n-butyl isocyanate in the presence of triethylamine in dichloromethane. Optically pure (2S,4aR,8aS)-(-)-and (2R,4aS,8aR)-(+)-cis,cis-decahydro-2-naphthols are resolved by the porcine pancreatic lipase-catalyzed acetylation of decahydro-2-naphthols with vinyl acetate in t-butyl methyl ether. Absolute configurations of (2S,4aR,8aS)-(-)-and (2R,4aS,8aR)-(+)-cis,cis-decahydro-2-naphthols are determined from the 19F NMR spectra of their Mosher's ester derivatives. (2S,4aR,8aR)-Trans,cis-and (2R,4aS,8aS)-trans,cis-decahydro-2- naphthols can't be resolved from the porcine pancreatic lipase-catalyzed acetylation of decahydro-2-naphthols with vinyl acetate in t-butyl methyl ether. For the inhibitory potency of Pseudomonas lipase, (2S,4aR,8aS)-cis,cis- decahydro-2-naphthyl-N-n-butylcarbamate is 3.5 times more potent than (2R,4aS,8aR)-cis,cis-decahydro-2-naphthyl-N-n-butylcarbamate; racemic cis,cis-decahydro-2-naphthyl-N-n-butylcarbamate is about the same with trans,cis-decahydro-2-naphthyl-N-n-butylcarbamate. These inhibitors also show similar effects on porcine pancreatic lipase.

Construction of a quaternary carbon at the carbonyl carbon of the cyclohexane ring

High SN2′ selectivity in the allylic substitution of cyclohexylidene ethyl picolinates with copper reagents prepared from RMgBr and CuBr·Me2S was realized by addition of ZnX2 (X = I, Br, Cl). Furthermore, ZnX2 accelerated the reaction with the bulky iPr reagent. The Royal Society of Chemistry 2010.

Efficient stereo- and regioselective hydroxylation of alkanes catalysed by a bulky polyoxometalate

Direct functionalization of alkanes by oxidation of C-H bonds to form alcohols under mild conditions is a challenge for synthetic chemistry. Most alkanes contain a large number of C-H bonds that present difficulties for selectivity, and the oxidants employed often result in overoxidation. Here we describe a divanadium-substituted phosphotungstate that catalyses the stereo- and regioselective hydroxylation of alkanes with hydrogen peroxide as the sole oxidant. Both cyclic and acyclic alkanes were oxidized to form alcohols with greater than 96% selectivity. The bulky polyoxometalate framework of the catalyst results in an unusual selectivity that can lead to the oxidation of secondary rather than the weaker tertiary C-H bonds. The catalyst also avoids wasteful decomposition of the stoichiometric oxidant, which can result in the production of hydroxyl radicals and lead to non-selective oxidation and overoxidation of the desired products.

Efficient and Practical Arene Hydrogenation by Heterogeneous Catalysts under Mild Conditions

An efficient and practical arene hydrogenation procedure based on the use of heterogeneous platinum group catalysts has been developed. Rh/C is the most effective catalyst for the hydrogenation of the aromatic ring, which can be conducted in iPrOH under neutral conditions and at ordinary to medium H 2 pressures (10 atm). A variety of arenes such as alkylbenzenes, benzoic acids, pyridines, furans, are hydrogenated to the corresponding cyclohexyl and heterocyclic compounds in good to excellet yields. The use of Ru/C, less expensive than Rh/C, affords an effective and practical method for the hydrogenation of arenes including phenols. Both catalysts can be reused several times after simple filtration without any significant loss of catalytic activity.
