Alkylidene carbenes undergo rapid inter- and intramolecular reactions and rearrangements, including 1,2-migrations of beta-substituents to generate alkynes. Their propensity for substituent migration exerts profound influence over the broader utility of allcylidene carbene intermediates, yet prior efforts to categorize 1,2-migratory aptitude in these elusive species have been hampered by disparate modes of carbene generation, ultrashort carbene lifetimes, mechanistic ambiguities, and the need to individually prepare a series of C-13-labeled precursors. Herein we report on the rearrangement of C-13-alkylidene carbenes generated in situ by the homologation of carbonyl compounds with [C-13]-Li-TMS-diazomethane, an approach that obviates the need for isotopically labeled substrates and has expedited a systematic investigation (C-13{H-1} NMR, DLPNO-CCSD(T)) of migratory aptitudes in an unprecedented range of more than 30 alkylidene carbenes. Hammett analyses of the reactions of 26 differentially substituted benzophenones reveal several counterintuitive features of 1,2-migration in alkylidene carbenes that may prove of utility in the study and synthetic application of unsaturated carbenes more generally.

In the present study, we reported the synthesis of a novel quinoline-based dendrimer-like ionic liquid. After characterization of the mentioned ionic liquid with suitable techniques such as Fourier transform infrared spectroscopy (FT-IR), energy dispersive X-ray spectroscopy (EDX), elemental mapping, thermogravimetric analysis (TGA) and derivative thermogravimetry (DTG), its catalytic performance was investigated in the synthesis of new pyridines with sulfonamide moiety via a cooperative vinylogous anomeric-based oxidation mechanism under mild reaction conditions. All target molecules were achieved in short reaction times and high yields.

Cuprous halides, best described as (CuX)(n) (X = Cl-, Br-, and I-) in their solid state, catalyse selective aerobic oxidation of alcohols with the assistance of both NMI (N-methylimidazole) and TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl), and the iodide generally demonstrates the highest activity, for example, in the oxidation of 1-octanol at ambient temperature under 24 h’ reaction. However, in the aerobic oxidation of benzylic alcohols, the chloride showed superiority to the iodide in that the aerobic oxidation was quantitatively completed within 3 h at ambient temperature whereas the iodide showed only about half the activity of the chloride analogue. By probing the system using electrochemistry, electric conductivity, and H-1 NMR titration, it was revealed that the surprising anomaly was due to the difference in the rate of forming active species, [Cu (NMI)(2)X(MeCN)], from the polymeric solid in a two-stage process. Substrates expansion of 11 benzylic alcohols indicated that CuCl/NMI/TEMPO system demonstrated quantitative conversion of benzylic alcohols into corresponding aldehydes within 3 h and showed great tolerance to the substituents on the phenyl ring of the substrates. Furthermore, electron-withdrawing substituent was beneficial to the oxidation and could offset the steric effect at orthro-substituent. Such a behaviour suggested that in the catalysis, increasing the acidity of the hydroxyl group (OH) of the substrates could ease the oxidation, which implied that the deprotonation via an internal pathway might be one of the rate-determining steps. Our results also showed that the anion halide participated actively in the catalysis by coordinating to Cu(I) in the active species.

A catalytic intermolecular amination of nonactivated tertiary C(sp(3))-H bonds (BDE of 96 kcal. mol(-1)) is reported for substrates displaying an activated benzylic site (BDE of 85 kcal.mol(-1)). The tertiary C(sp(3))-H bond is selectively functionalized to afford alpha, alpha, alpha-trisubstituted amides in high yields. This unusual site-selectivity results from the synergistic combination of Rh-2(Stfpttl)(4), a rhodium(II) complex with a well-defined catalytic pocket, with tert-butylphenol sulfamate (TBPhsNH(2)), which leads to a discriminating rhodium-bound nitrene species under mild oxidative conditions. This catalytic system is very robust, and the reaction was performed on a 50 mmol scale with only 0.01 mol % of catalyst. The TBPhs group can be removed under mild conditions to afford the corresponding NH-free amines.

An intramolecular carbometallation of a triple bond promoted by electrochemistry and mediated by nickel catalysis is described. This domino process transforms various aryl halides bearing a propargyl chain into substituted heterocycles in one single operation, with high stereoselectivities and in good to high yields. This reaction, characterized by a cyclic voltammetry set of experiments, proceeds following a syn-exo-dig cyclization process. When run at 80 degrees C, vinylbenzofuranes that are suitable substrates for cycloaddition reactions are obtained.

3,4,7,8-tetrahydro-3,3-dimethyl-11-aryl-2H-pyridazino[1,2-a]indazole-1,6,9(11H)-triones 5a-j were synthesized by a one-pot cyclocondensation of four components such as succinic anhydride, hydrazine hydrate, benzaldehyde derivatives and dimedone at room temperature through a multi-component reaction and solvent-free condition by using 1-methyl imidazolium trinitromethanide {[HMIM]C(NO2)(3)} as a very effective ionic liquid catalyst. All synthesized compounds which are soluble in DMSO were subjected to antibacterial activity assay against Escherichia coli, Salmonella enteritidis, Staphylococcus aureus, and Bacillus cereus. Results showed that the compounds had antibacterial activity against some bacteria tested. In addition, the antioxidant activity of the compounds was evaluated by DPPH free radical scavenging assay. Our results indicated that most of the compounds had excellent dose-dependent antiradical properties. Based on obtained data, the compounds possessed moderate to excellent bactericidal effect on both Gram-positive and Gram-negative bacteria. Moreover, the compounds 5b and 5g exhibited the most anti-proliferative potencies against MCF-7 (breast carcinoma), A549 (non-small lung carcinoma) and AGS (gastric carcinoma) cell lines.

An efficient method for the synthesis of a new highly substituted pyrrolidinone derivative is developed via a three-component one-pot reaction of aniline, diethyl acetylenedicarboxylate, and 4-anisaldehyde. The structure of ethyl 4-hydroxy-2-(4-methoxyphenyl)-5-oxo-1-phenyl-2,5-dihydro-1H-pyrrole-3-carboxylate is confirmed by FTIR, H-1 and C-13 NMR spectroscopy. Unambiguous evidence for the structure of the synthesized product is obtained from the single crystal X-ray analysis. The comparison of both its molecular structure and intermolecular interactions with the previously known analogous compounds reveals that the mutual syn- or antiperiplanar orientation of ester C=O and pyrrolinone-bound OH is related to the type of molecular dimers formed in the solid state. The geometrical structure, the HOMO-LUMO analysis (electrophilicity index), H-1 and C-13 chemical shifts of the desired product are also calculated by DFT at the B3LYP level with the 6-31++G(d,p) basis set. The calculated chemical shifts are in compliance with the experimental data.

A number of monoazo dyes were synthesized by the reaction of 4-aminoacetophenone with different substituted benzaldehydes to give a new series of chalcone derivatives. The diazonium salts of these chalcones then allowed to react with thiobarbituric acid to produce the appropriate azo dye. The structures of the newly synthesized dyes were assigned by IR, NMR spectral data. IR study confirmed the existence of azo-dioxothioxo tautomer in the solid phase while H-1 NMR study indicated the predominance of azoenol-oxothioxo or hydrazo-dioxothioxo tautomers. The geometries of the azo and hydrazo tautomeric forms and their electronic absorption of the dyes were optimized at B3LYP/6-311G level of theory. All the azo compounds were evaluated for their dyeing performance on polyester fibers, and PET. All the synthesized dyes gave moderate to excellent fastness properties on PET fiber. The effects of the nature of the substituents on the color and dyeing properties of these dyes have been evaluated. The mechanism of dyeing polyester fiber was discussed.

Series of highly polar stilbene (1a-e), diphenylbutadiene (2a-c) and phenylethenyIthiophene (3a-c) derivatives were prepared via Horner-Wadsworth-Emmons method with a view to produce new and efficient materials for second harmonic generation (SHG) in the solid-state. The single-crystal X-ray structures of compounds 1-3 reveal extensive polymorphism and a peculiar photodimerization of the 2-chloro-3,4-dimethoxy-4′-nitrostilbene derivative 1a to afford two polymorphs of tetra-aryl cyclobutane 4. The stilbene congeners 2-chloro-3,4-dimethoxy-4′-nitrostilbene (1a. non-centro), 5-bromo-2-hydroxy-3-nitro-4′-nitrostilbene (1b) and 4-dimethylamino-4′-nitrostilbene (1e), as well as 4′-fIuoro-4 ”-nitro-1,4-diphenyl-1,3-butadiene (2a) present the ideal, non-centrosymmetric arrangement of the chromophores for nonlinear optical (NLO) activity. Compounds lb and 2a exhibit only relatively Low intensity for second harmonic generation (0.04 and 0.18 times that of urea reference, respectively), while the stilbene polymorph 1a.non-centro shows NLO activity of over 32 times that of urea. In addition, the conjugated diaromatic compounds 1-3 display fluorescence behaviour in CH2Cl2 solutions with the exception of stilbene derivative 1b.
