Reaction of 3-O-benzyl-1,2-O-isopropyl-idene-α-xylo-pentodialdo-1,4-furan-ose with N,N-diethyl-2-(dimethyl-sulfuranil-idene)acetamide gave stereoselectively an ep-oxy-amide, which was regioselectively opened by NaN(3) in dimethyl formamide to give the title compound, C(21)H(30)N(4)O(6). X-ray crystallography confirmed the relative stereochemistry of the title compound and the absolute configura...

In this study, micron-sized pored membranes, based on the co-polymer polyvinylidene difluoride hexafluoropropylene (PVdF-HFP) were prepared via phase inversion techniques. The aim of the approach was to find less harmful and less toxic solvents to fabricate such films. Therefore, the Hansen solubility approach was used to identify safer and less toxic organic solvents for the phase inversion pr...

Two novel Zn(II) metal-organic frameworks (MOFs) constructed by trinuclear-triangular and paddle-wheel units, namely {[Zn(5)(dmtrz)(3)(IPA)(3)(OH)]·DMF·H(2)O}(n) (MAC-4, Hdmtrz = 3,5-dimethyl-1H-1,2,4-triazole, H(2)IPA = isophthalic acid, DMF = dimethyl formamide) and {[Zn(5)(dmtrz)(3)(OH-IPA)(3)(OH)]·DMF·5H(2)O}(n) (MAC-4-OH, OH-H(2)IPA = 5-hydroxyisophthalic acid), were solvothermally synthes...

In the title compound, [Cd(C(10)H(9)N(4)O(2)S)(2)(C(12)H(12)N(2))]·2C(3)H(7)NO, the Cd(II) ion lies on a twofold rotation axis, is six-coordinated by N atoms, and displays a trigonal-prismatic geometry arising from the two sulfadiazinate ligands and one 4,4'-dimethyl-2,2'-bipyridine ligand. Both ligands are bidentate and coordinate via their N atoms. The O and carbonyl C atoms of the dimethyl-f...

Effect of different solvents; dimethyl-sulfoxide (DMSO), dimethyl formamide (DMF), methanol, tween 80 and acetone on morphology, cytology and reproduction of Aspergillus flavus, A. parasiticus, A. fumigatus and A. niger was assayed for standardization of a suitable organic solvent for test/antimicrobial compound in antimicrobial assays. Comparison of antimicrobial sensitivity methods was also m...

The title compound, [-Si(C(12)H(9))(2)OSi(CH(3))(2)O-](2), was obtained unintentionally as the product of an attempted crystallization of caesium bis-(biphenyl-2,2'-di-yl)fluoro-silicate from dimethyl-formamide. In the crystal, the mol-ecule is located on an inversion center and the siloxane ring adopts a twist-chair conformation with the two dimethyl-substituted Si atoms lying 0.7081 (5) Å out...

The Camphor sulphonic acid doped polyaniline (CSA-PANi)is synthesized by chemical polymerization method and then characterized by using UV-Visible and FTIR. The surface morphology is studied by SEM and AFM techniques. The degree of crystallinity of PANiis studied by XRD and redox behaviour by cyclic voltametry. Thermal stability of the doped polymer is investigated by TGA and DSC.The fluorescen...

Planarity of the XC(=)NHY linkage has been investigated in unprecedented detail in a number of relatively simple compounds, including formamide (X = Y = H), acetamide (X = CH3, Y = H), urea (X = NH2, Y = H), carbamic acid (X = OH, Y = H), and methyl carbamate (X = OCH3, Y = H). Reliable estimates of the equilibrium structures of formamide, cyanamide, acetamide, urea, carbamic acid, methylamine,...
