Figure presented In this paper, a novel synthesis of tertiary amides from anionically activated aromatic trifluoromethyl groups is presented. Anionically activated trifluoromethyl groups react with secondary amines under aqueous conditions to afford tertiary amides. The mechanism involves initial elimination of hydrogen fluoride by an E1cB mechanism to afford an electrophilic quinone methide- or azafulvene-type intermediate that reacts with secondary amines under aqueous conditions to afford the tertiary amide in good yield (up to 99%).

Photoluminescent diamino-substituted dinaphthopentalenes were synthesized successfully by the treatment of in situ prepared dinaphthocyclooctadiyne with lithium amide. This reaction involves a series of transformations including the nucleophilic addition of the lithium amide to a triple bond of the cyclooctadiyne moiety, transannulation, protonation of the resulting pentalene anion, and the nucleophilic substitution of the pentalene core with the lithium amide. In this procedure, a novel double amination step plays a key role. When the diamino-substituted dinaphthopentalenes were irradiated with UV light in toluene, fluorescence was observed at around 580 nm (phiF < 0.03). A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

The thermodynamics for intermolecular hydroamination of vinylarenes with arylamines have been measured directly by conducting the addition processes, as well as cleavage of the addition products, under conditions in which amine, vinylarene, and phenethylamine are all present. The reaction of N-methylaniline with styrene is exothermic by about 10 kcal/mol but nearly thermoneutral in free energy. The free energies for additions of various primary arylamines to styrene and for additions of primary arylamines to indene, dihydronaphthalene, and two vinylarenes range from 1.3 to -3.5 kcal/mol (K = 0.16-155 M-1). The steric properties of the nucleophile significantly influenced the equilibrium constant for addition, but the electronic properties of the nucleophile had a minor effect on this equilibrium constant. These measurements have led to the first successful intermolecular addition of aniline to indene and 1,2-dihydronaphthalene and shed light on factors requiring consideration when choosing substrates and reaction conditions for this transformation.

The air- and water-stable pi-allyliridium C,O-benzoate modified by (S)-tol-BINAP, (S)-Ir-II, catalyzes highly regio- and enantioselective Tsuji-Trost-type aminations of racemic branched alkyl-substituted allylic acetates using primary or secondary (hetero)aromatic amines. Specifically, in the presence of (S)-Ir-II (5 mol%) in DME solvent at 60-70 C, alpha-methyl allyl acetate 1a (100 mol%) reacts with primary (hetero)aromatic amines 2a-2l (200 mol%) or secondary (hetero)aromatic amines 3a-3l (200 mol%) to form the branched products of allylic amination 4a-4l and 5a-5l, respectively, as single regioisomers in good to excellent yield with uniformly high levels of enantioselectivity. As illustrated by the conversion of heteroaromatic amine 3m to adducts 6a-6g, excellent levels of regio- and enantioselectivity are retained across diverse branched allylic acetates bearing normal alkyl or secondary alkyl substituents. For reactants 3n-3p, which incorporate both primary and secondary aryl amine moieties, regio- and enantioselective amination occurs with complete site-selectivity to furnish adducts 7a-7c. Mechanistic studies involving amination of the enantiomerically enriched, deuterium-labeled acetate 1h corroborate C-N bond formation via outer-sphere addition.

Optimization of the pharmacokinetic properties for a series of benzoxazolone derivatives led to the identification of 9b, which showed anxiolytic effect in a rat model. However, 9b, like known benzodiazepines, induced motor impairment. Investigation into the cause of this unexpected side effect and management of 9b off-target binding affinity led to the identification of 10d, which showed oral anxiolytic effect in the rat model with improved safety profile.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 33282-15-4, you can also check out more blogs about33282-15-4

A series of molybdenum pincer complexes has been shown for the first time to be active in the catalytic hydrogenation of amides. Among the tested catalysts, Mo-1a proved to be particularly well suited for the selective C-N hydrogenolysis of N-methylated formanilides. Notably, high chemoselectivity was observed in the presence of certain reducible groups including even other amides. The general catalytic performance as well as selectivity issues could be rationalized taking an anionic Mo(0) as the active species. The interplay between the amide CO reduction and the catalyst poisoning by primary amides accounts for the selective hydrogenation of N-methylated formanilides. The catalyst resting state was found to be a Mo-alkoxo complex formed by reaction with the alcohol product. This species plays two opposed roles-it facilitates the protolytic cleavage of the C-N bond but it encumbers the activation of hydrogen.

Cu-containing layered double hydroxides were synthesized by co-precipitation method using base solution (NaOH and Na2CO3) with different concentration of carbonate ions. The influence of the precipitating agent concentration on formation of hydrotalcite phase was investigated. Characterization of the surface of the obtained samples calcined at 450 C and 650 C was performed by x-ray photoelectron spectroscopy. Catalysts based on Cu-layered double hydroxides were investigated in N-methylation of p-anisidine by methanol obtaining N-methyl-p-anisidine using autoclave reactor. Effect of precipitating agent concentration during synthesis of the Cu-layered double hydroxide on the catalyst performance was studied.
