Thermodynamic study for the stability of aromatic complexes formation derived from the reaction of 4-dimethyl amino benzaldehyde with diazotized dinitro aniline reagents

This research includes the preparation of aromatic azoimine complexes resulting from the coupling reaction (4) of Schiff bases with diazotized dinitroaniline reagent. Ultraviolet spectra, infrared spectra, and melting points are among the most important p

Manganese catalyzed reductive amination of aldehydes using hydrogen as a reductant

A one-pot two-step procedure was developed for the alkylation of amines via reductive amination of aldehydes using molecular dihydrogen as a reductant in the presence of a manganese pyridinyl-phosphine complex as a pre-catalyst. After the initial condensation step, the reduction of imines formed in situ is performed under mild conditions (50-100 °C) with 2 mol% of catalyst and 5 mol% of tBuOK under 50 bar of hydrogen. Excellent yields (>90%) were obtained for a large combination of aldehydes and amines (40 examples), including aliphatic aldehydes and amino-alcohols.

Divergent Coupling of Alcohols and Amines Catalyzed by Isoelectronic Hydride MnIand FeIIPNP Pincer Complexes

Herein, we describe an efficient coupling of alcohols and amines catalyzed by well-defined isoelectronic hydride MnIand FeIIcomplexes, which are stabilized by a PNP ligand based on the 2,6-diaminopyridine scaffold. This reaction is an environmentally benign process implementing inexpensive, earth-abundant non-precious metal catalysts, and is based on the acceptorless alcohol dehydrogenation concept. A range of alcohols and amines including both aromatic and aliphatic substrates were efficiently converted in good to excellent isolated yields. Although in the case of Mn selectively imines were obtained, with Fe—exclusively monoalkylated amines were formed. These reactions proceed under base-free conditions and required the addition of molecular sieves.

Grinding synthesis of schiff bases combined with infrared irradiation

Solid-phase synthesis combined with infrared irradiation promoted the formation of a series of Schiff bases in the condensation reaction between substituted benzaldehydes and anilines, in the solvent free. Benzaldehydes and anilines, containing either electron withdrawing or electron-releasing groups, were evaluated their substituent effect on the formation of the Schiff bases. Moreover, this new procedure is environmentally benign because no solvent was employed in the transformations.

Synthesis and NMR characterization of two novel anthracene-derived BIS-aminophosphonates. Basic hydrolysis of some aminophosphonate derivatives

The synthesis of two novel bis-aminophosphonates bearing anthracene rings-bis[N-methyl(diethoxyphosphonyl)-1-(9-anthryl)]benzidine (3) and 4,4-bis[N-methyl(diethoxy-phosphonyl)-1-(9-anthryl)]diaminodiphenylmethane (4)-via the Kabachnik-Fields reaction is reported. The compounds have been characterized by elemental analysis, TLC, IR, NMR (1H, 13C, 31P) and fluorescent spectra. The reaction leads to a mixture of the two possible forms (meso and racemic), with predominant formation of one of the diastereomers. The recrystallized compounds 3 and 4 consist of only one diastereomer. A racemization at the chiral centers and a cleavage of the C-P bond are observed in the alkaline hydrolysis of the new compound 4 and three previously described aminophosphonate derivatives 5-7.

An expeditious one-pot synthesis of substituted phenylazetidin-2-ones in the presence of zeolite

In this study, one-pot rapid and efficient series of phenylazetidin-2-ones were synthesized from N,N-dimethylaminobenzaldehyde, different substituted aromatic amines and phenylacetyl chloride in the presence of zeolite catalyst under microwave irradiation. We also reported schiff bases (1a-j) by classical and conventional microwave technique. The titled compounds are evaluated for their antimicrobial properties. The activities are due to Ci=O, Ci-N, linkages in 2-azetidinones. All the compounds have shown comparable antibacterial activities.

Inhibition effect of nitrogen containing ligands on corrosion of aluminium in acid media with and without KCl

Mass loss and thermometric methods have been used to study the corrosion inhibition of aluminium in HCl solution by nitrogen containing ligands viz. N-(4-N,N-dimethylaminobenzal)-p-anisidine (SB1), N-(4-N,N- dimethylaminobenzal)-p-toluidine (SB2) and N-(4-N,N- dimethylaminobenzal)-2,4-dinitroaniline (SB3). Results of inhibition efficiencies obtained from these two methods are in good agreement and have been found to be dependent upon the concentration of inhibitors as well as concentration of acids. Inhibition efficiency of synthesized ligands has also been studied in the presence of KCl with inhibitors.

Substituent cross-interaction effects on the electronic character of the C=N bridging group in substituted benzylidene anilines - Models for molecular cores of mesogenic compounds. A 13C NMR study and comparison with theoretical results

13C NMR chemical shifts δc(C=N) were measured in CDCl 3 for a wide set of mesogenic molecule model compounds, viz. the substituted benzylidene anilines P-X-C6H4CH=NC 6H4-p-Y (X = NO2, CN, CF3, F, Cl, H, Me, MeO, or NMe2; Y = NO2, CN, F, Cl, H, Me, MeO, or NMe2). The substituent dependence of δc(C=N) was used as a tool to study electronic substituent effects on the azomethine unit. The benzylidene substituents X have a reverse effect on δc(C=N): electron-withdrawing substituents cause shielding, while electron-donating ones behave oppositely, the inductive effects clearly predominating over the resonance effects. In contrast, the aniline substituents Y exert normal effects: electron-withdrawing substituents cause deshielding, while electron-donating ones cause shielding of the C=N carbon, the strengths of the inductive and resonance effects being closely similar. Additionally, the presence of a specific cross-interaction between X and Y could be verified. The electronic effects of the neighboring aromatic ring substituents systematically modify the sensitivity of the C=N group to the electronic effects of the benzylidene or aniline ring substituents. Electron-withdrawing substituents on the aniline ring decrease the sensitivity of δc(C=N) to the substitution on the benzylidine ring, while electron-donating substituents have the opposite effect. In contrast, electron-withdrawing substituents on the benzylidene ring increase the sensitivity of δc(C=N) to the substituent on the aniline ring, while electron-donating substituents act in the opposite way. These results can be rationalized in terms of the substituent-sensitive balance of the electron delocalization (mesomeric effects). The present NMR characteristics are discussed as regards the computational literature data. Valuable information has been obtained on the effects of the substituents on the molecular core of the mesogenic model compounds.
