Upon treatment with a combination of HFIP and an organic sulfonic acid, alkenes behave as Br°nsted bases and protonate to give carbocations which can be trapped by electron-rich arenes. The reaction constitutes a Friedel-Crafts hydroarylation which proceeds with Markovnikov selectivity and is orthogonal to traditional metal-catalyzed processes. Intermolecular transfer hydrogenation and hydrothiolation under analogous conditions are also demonstrated.

The asymmetric modularly designed supramolecular organocatalytic nitro olefin-ketone Michael addition of a variety of functionally rich nitro olefins with ketones was explored. The modularly designed supramolecular organocatalytic Michael reaction is characterized by a high rate, high chemoselectivity, high diastereoselectivity, high enantioselectivity, mild reaction conditions, readily available substrates/catalysts with simple operations, and excellent yields with a broad spectrum of functionally rich substrates. This method constitutes an alternative to previously known organocatalytic Michael reactions. We demonstrate the power of a supramolecular organocatalyst as an excellent stimulant for the highly reactive Michael addition of various ketones with functionally rich (E)-nitro olefins under ambient conditions to furnish enantiomerically pure carbamates and tetrahydroacridines; Cbz = benzyloxycarbonyl.

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 1119-97-7, molcular formula is C17H38BrN, introducing its new discovery. Application In Synthesis of MitMAB

The invention relates to compositions including a charged oligo-phenylene ethynylene singlet-oxygen sensitizer and an oppositely-charged surfactant, which show an enhanced biocidal activity relative to a comparable concentration of the oligo-phenylene ethynylene without the oppositely-charged surfactant. The enhancement of biocidal activity is observed with an anionic oligo-phenylene ethynylene in the presence of a cationic surfactant such as TTAB, and with a cationic oligo-phenylene ethynylene in the presence of an anionic surfactant such as SDS.

Synthetic Route of 3779-42-8, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 3779-42-8, name is 3-Bromo-N,N,N-trimethylpropan-1-aminium bromide. In an article，Which mentioned a new discovery about 3779-42-8

A novel asymmetrical gemini ionic liquid, 1-(3-(trimethylammonio)prop-1-yl)-3-methylimidazolium bis(dicyanamide) ([N111C3MIM][N(CN)2]2), was synthesized and characterized by 1H NMR, 13C NMR. Thermal stability of [N111C3MIM][N(CN)2]2 was investigated through thermogravimetric analysis under pure nitrogen atmosphere. Heat capacity of pure [N111C3MIM][N(CN)2]2 was measured using differential scanning calorimetry in the temperature range 298.15?423.15 K and enthalpy HT-H298.15K, and entropy ST-S298.15K were obtained. Densities and viscosities were measured for the binary system of [N111C3MIM][N(CN)2]2 and isopropanol (IPA) over the entire range of mole fractions at various temperatures from 283.15 to 333.15 K under the pressure of 0.101 MPa. Moreover, the excess molar volumes (VmE) and the viscosity deviations (Deltaeta) for the binary mixtures were determined and well fitted to the Redlich?Kister polynomials. The negative values of VmE and Deltaeta result from strong self-association and weak hydrogen bonding interaction between the molecules of [N111C3MIM][N(CN)2]2 and IPA. Excess Gibbs energy of activation (DeltaG*E) of viscous flow for the present binary mixtures were also calculated. Results have been discussed in terms of molecular interactions and structures.

The development of a method for the optimization of chiral ligands for the steric steering of enantioselective Cu-catalyzed conjugate additions of Zn-alkyls to enones is described. The method is based on combinatorial principles and solid-phase techniques. It includes the combinatorial synthesis of chiral bispidine-derived ligands embodying a phosphoramidite group on the solid phase and their investigation in immobilized form in the conjugate addition of ZnEt2 to cyclohexenone as test reaction. The best identified ligands were also synthesized separately and investigated in its soluble form. The results obtained for the polymer-bound ligands correctly mirrored the performance of the soluble ligands. The library embodied members giving ee values varying between 3 and 67%. The “positional scanning” approach proved to be invalid for the study of the ligand system, indicating that this approach in general should be applied with care. Taken together, the method allowed for rapid and efficient optimization of the ligands and led to the development of the first enantioselective, Cu-catalyzed conjugate addition reaction with a polymer-bound ligand.

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， name: H-HoPro-OH, Which mentioned a new discovery about 3105-95-1

New approach is developed to the synthesis of cyclic amino acids derivatives. Unsaturated tertiary amines react with ethyl diazoacetate under the catalysis by copper catalyst Cu(F3acac)2 leading to the formation of products of [2,3]-sigmatropic rearrangement which via the metathesis of double bonds undergo a ring closure. The subsequent hydrogenation of compounds obtained furnished esters of 6- and 7-membered cyclic alpha-amino acids. Besides the racemic also optically active compounds were obtained, in particular, esters of (R)- and (S)-pipecolic acid.

Functionalised hydroxylamine derivatives of (S)-proline and (R)-pipecolic acid have been prepared using a Cope elimination. These undergo reverse Cope elimination onto a pendant double bond to give bicyclic lactam and lactone N-oxides containing three contiguous chiral centres, this extends the scope and applicability of the reverse Cope elimination in the synthesis of heterocyclic systems by incorporation of the lactone and lactam structural motifs.
