Abstract. Synthesis of 1,1′-(3,4-diphenylthieno[2,3-b]thiophene-2,5-diyl)diethanone (4) is reported structure of compound 4 was deduced by 1 H-NMR, 13 C-NMR, FT-IR, MS, microanalysis, and single-crystal X-ray diffraction. Compound crystallizes in the monoclinic space group P21/n with a = (7) Å, b = (7) Å, c = (15) Å, α = 90°, β = (2)°, γ = 90°, V. Abstract: A series of novel metal complexes containing metal atoms such as Zn, Co, Cu, Cd, Ni, Mg and Sn have been synthesized from 3-(1,3-benzoxazolyl) synthesized ligand was well characterized by IR, 1H-NMR and mass spectrometry. The electrochemical properties were studied by cyclic voltammetric analysis.

Some of these exceptions arise because the addition reaction is reversible, dissociation being particularly important at high temperature. The exo configuration is generally more stable than the endo and, given time to reach equilibrium (cf. Section A), the exo isomer may be the major adduct. with thiazole derivatives []. These pharmacological activities have been attracted special attention to prepare a new class of thiazole derivatives carrying antipyrinyl moiety because of their applications in the field of phar- maceuticals [] and antibacterials []. The present work reports the synthesis of certain thiazole derivatives.

Categories: Synthesis of N-Heterocycles > Synthesis of 1,3,5-triazines. Recent Literature. A simple and efficient method for the base-mediated synthesis of unsymmetrical 1,3,5-triazinamines uses readily available imidates, guanidines, and amides or aldehydes . compounds prompted us to synthesize some new 1,2,4-triazoleone derivatives bearing benzene methane sulfonamides. LITERATURE SURVEY Several synthetic methods have been reported in the literature for [1, 2, 4-triazol]one and a few of them are discussed below: Curtius and Heidenrich [89] reported the formation of 4-amino-.

Recent Literature. A simple, efficient, and mild method for the synthesis of substituted 1,2,4-triazoles from hydrazines and formamide proceeds smoothly under microwave irradiation in the absence of a catalyst and shows excellent functional-group tolerance.

In particular, compounds 17a-c were obtained through a 1,3-dipolar cycloaddition of the proper azido-derivatives (13a-c) with malononitrile (14) in the presence of sodium ethoxide.

5-Aminosubstituted- [1,3]oxazolecarbonitrile derivatives 18a-c were prepared through the van Leusen oxazole synthesis, according to the general method reported by Freeman and Kim [].Author: Ilaria Frasson, Virginia Spanò, Simona Di Martino, Matteo Nadai, Filippo Doria, Barbara Parrino, Ann.

The macrocycle with three methylphosphinates, NOTMP, appeared to be a very promising ligand for monitoring MgII in biological samples by 31P NMR spectroscopy. The 31P resonances of the free ligand and the MgII complex were well resolved, in.

A simple condensation afforded some new 3-thioxo-1,2,4-triazinone derivatives (4, 6 and 8). Utilizing a facile condensation of (E)(4’-bromo styryl)oxobuteneoic acid with thiosemicarbazide, dithioic formic acid hydrazide, and thiocarbahydrazide in different conditions.

Structures of these compounds were confirmed by elemental and spectral analysis. Michael reactions of methyl (ethyl) 1-benzyloxopiperidinecarboxylates with a number of α,β-unsaturated carbonyl compounds result in formation of 6- and 6,8-substituted methyl (ethyl) 3-benzyloxoazabicyclo[]nonanecarboxylates.

Stereochemical aspects of these reactions were studied, and some further transformations of the products were performed.
