Synthesis of nitroalkenes involving a cooperative catalytic action of iron(III) and piperidine: A one-pot synthetic strategy to 3-alkylindoles, 2H-chromenes and N-arylpyrrole

An efficient and simple strategy has been developed to synthesize various substituted nitroalkenes involving a cooperative catalytic system of FeCl 3 and piperidine. This dual catalytic protocol simultaneously activates both electrophile and nucleophile and works under mild reaction conditions so that many sensitive functional groups were tolerated. Moreover, this cooperative catalytic reaction is also suitable for various one-pot reactions involving nitroalkenes such as, 2H-chromenes, N-arylpyrrole and Michael reaction with indole. Notably, this method is low-cost, efficient and environmentally friendly. Copyright

Palladium-catalyzed synthesis of substituted nitroolefins

A one-pot protocol toward several substituted nitroolefins 4 and 6 starting with substituted acetones 2 and 5 was described. A facile process was carried out for the triflation of substituted acetones 2 and 5 with triflic anhydride (Tf2O) under the basic condition (Cs2CO3) and then palladium-catalyzed cross-coupling of enol triflates 3 with NaNO 2 and BINAP in the presence of phase-transfer reagents (n-Bu 4NBr) under the refluxing 1,2-dimethoxyethane (DME) in acceptable yields.

Ambiphilic dual activation role of a task-specific ionic liquid: 2-hydroxyethylammonium formate as a recyclable promoter and medium for the green synthesis of β-nitrostyrenes

A cost-effective task-specific ionic liquid, 2-hydroxyethylammonium formate, efficiently promotes the condensation of nitroalkanes with various aldehydes to produce β-nitrostyrenes in high to excellent yields at room temperature. This reaction does not involve any hazardous organic solvent and toxic catalyst. The ionic liquid is recovered and recycled for subsequent reactions. In addition, a novel mechanism has been proposed invoking ambiphilic dual activation influence of the ionic liquid.

An efficient synthesis of (E)-nitroalkenes catalyzed by recoverable diamino-functionalized mesostructured polymers

A clean, efficient, and simple method has been developed for synthesis of (E)-nitroalkenes using FDU-ED as an efficient catalyst. The reactions proceeded with moderate to high yields (60-96%) under mild conditions. The catalyst FDU-ED is recyclable and can be reused more than seven times without significant loss of activity and selectivity.

The yeast-mediated reduction of nitrostyrenes in organic solvent systems

A range of nitrostyrenes have been reduced with dried baker's yeast in an organic solvent system. It was found that the reduction proceeded smoothly to give the corresponding nitroalkanes in good yield and with higher efficiency than the corresponding aqueous reaction system. No evidence for reduction of the nitro group was observed. In the case of β-methyl nitrostyrenes, racemic mixtures were formed, and it was shown that this is not due to racemization of the product.

Kinetics of reaction of para-substituted β-nitrostyrenes and β-methyl-β-nitrostyrenes with n-butylamine

The kinetics of addition of n-butylamine to β-nitrostyrene and β-methyl-β-nitrostyrene and their para-substituted derivatives in acetonitrile at four different temperatures have been followed spectrophotometrically.The order in is unity and in (n-butylamine) it is non-integral.On the basis of the observed kinetic data, a stepwise mechanism involving the formation of zwitterionic addition complex in an equilibrium step followed by conversion into the reaction product via proton transfer in catalytic route by the amine has been proposed.The study of effect of substituents in these reactions shows that the electron-withdrawing substituents accelerate the reaction and electronreleasing substituents retard it.Good Hammett correlations have been observed in both the reaction series.

ACETONYLATION AROMATIQUE HOMOLYTIQUE

Treatment of monosubstituted benzene derivatives with acetone and manganese(III) acetate in acetic acid gave rise to products of homolytic aromatic substitution in fairly good yields and high purity except for toluene.Isomer distribution, relative rates and partial rate factors were determeined for toluene, anisole, chlorobenzene, bromobenzene and benzonitrile.A Hammet plot of the logarithm of the partial rate factors for meta and para positions vs. ?-constants gave a slope ρ of -1.74 +/- 0.40 (confidence interval at the level 95percent).When using ?+-constants the slope becomes ρ+ = -1.25 +/- 0.36.The negative velues of ρ and ρ+ indicated that the acetonyl radical has an appreciable electrophilic character.
