Dynamic 1H NMR Study Around the Carbon–Carbon Double Bonds and Carbon–Carbon Single Bonds in a Particular Phosphorous Ylide and 2,5-Dihydro-5,5-Diaryl-2-Thio-1H-Imidazoles

Stable crystalline phosphorus ylides are obtained in excellent yields from the 1:1:1 addition reactionbetween hydantoins or thiohydantoins and dialkyl acetylenedicarboxylates in the presence oftriphenylphosphine. These phosphoranes undergo smooth intramolecular Wittig reaction followedby an electrocyclic ring opening to produce dialkyl (E)-2-(2,5-dihydro-5,5-diaryl-2-thioxo-1H-imidazol-4-yl)fum...

Two isomeric reaction products: hydrogen-bonded sheets in methyl 4-(5-amino-3-phenyl-1H-pyrazol-1-yl)-3-nitrobenzoate and hydrogen-bonded chains of edge-fused rings in methyl 3-nitro-4-[(5-phenyl-1H-pyrazol-3-yl)amino]benzoate.

In methyl 4-(5-amino-3-phenyl-1H-pyrazol-1-yl)-3-nitrobenzoate, C(17)H(14)N(4)O(4), the molecules are linked into complex sheets by a combination of N-H...N, N-H...O and C-H...O hydrogen bonds. In the isomeric methyl 3-nitro-4-[(5-phenyl-1H-pyrazol-3-yl)amino]benzoate, molecules exhibit a polarized molecular-electronic structure and are linked into chains of edge-fused rings by a combination of...

{N-[1-(1H-Benzimidazol-2-yl)ethyl­idene-κN 3]-3-(1H-imidazol-1-yl)propan-1-amine-κN}dibromidomercury(II)

In the title compound, [HgBr(2)(C(15)H(17)N(5))], the Hg(II) ion is tetra-hedrally coordinated by two N atoms of the N-[1-(1H-benzimidazol-2-yl)ethyl-idene-κN]-3-(1H-imidazol-1-yl)propan-1-amine ligand, and two bromide anions. Inter-molecular benzimidazole-imidazole N-H⋯N hydrogen bonds link the mol-ecules into helical chains along the b-axis direction and C-H⋯Br hydrogen bonds link these chain...

Determination of membrane Peptide orientation by 1H-detected 2H NMR spectroscopy.

We demonstrate the application of the proton inverse detected deuteron (PRIDE) NMR technique to the measurement of the orientation of membrane-bound peptides with enhanced sensitivity. Gramicidin D, a transmembrane peptide, and ovispirin, a surface-bound peptide, were used as model systems. The peptides were 2H-labeled by 1H/2H exchange and oriented uniaxially on glass plates. The directly dete...

4-Amino-1H-1,2,4-triazol-1-ium nitrate

The non-centrosymmetric crystal structure of the novel semi-organic title compound, C(2)H(5)N(4) (+)·NO(3) (-), is based on alternating layers of 4-amino-1H-1,2,4-triazolinium cations (formed by parallel chains of cations mediated by weak C-H⋯N hydrogen bonds) and nitrate anions inter-connected via linear and bifurcated N-H⋯O hydrogen bonds and weak C-H⋯O hydrogen bonds. N-H⋯N hydrogen bonds li...
