An efficient synthesis of N-substituted 3-nitrothiophen-2-amines
A novel protocol for the synthesis of 3-nitro-N-aryl/alkylthiophen-2-amines in good yields from the reaction of α-nitroketene N,S-aryl/alkylaminoacetals and 1,4-dithiane-2,5-diol in the presence of K2CO3 in refluxing ethanol is described. This transformation generates two C-C bonds in a single operation and presumably proceeds through a reaction sequence comprising 2-mercaptoacetaldehyde genera...
متن کاملCrystal structure of 2-hydroxy-N-(2-hydroxyethyl)-N-{2-hydroxy-3-[(E)-N-hydroxyethanimidoyl]-5-methylbenzyl}ethanaminium acetate monohydrate
The structure of the title hydrated mol-ecular salt, C14H23N2O4 (+)·C2H3O2 (-)·H2O, was determined as part of a wider study on the use of the mol-ecule as a polydentate ligand in the synthesis of Mn(III) clusters with magnetic properties. The cation features intra-molecular O-H⋯N and N-H⋯O hydrogen-bond inter-actions. The crystal structure features a range of inter-molecular hydrogen-bonding in...
متن کاملCrystal structure of (E)-3-(5-bromo-2-hydroxyphenyl)acrylaldehyde
The title compound, C9H7BrO2, displays a trans configuration with respect to the C=C double bond and is essentially planar [maximum deviation from the least-squares plane through all non-H atoms = 0.056 (4) Å]. The vinyl-aldehyde group adopts an extended conformation wih a C-C-C-C torsion angle of 179.7 (4)°. In the crystal, mol-ecules are linked by classical O-H⋯O and weak C-H⋯O hydrogen bonds...
متن کاملCrystal structure of (E)-N′-(3-fluoro-2-hydroxybenzylidene)isonicotinohydrazide
In the title compound, C13H10FN3O2, the mol-ecule has an E conformation with respect to the C=N bond of the hydrazone bridge. The dihedral angle between the isonicotinoyl and fluoro-phenol moieties is 4.03 (4)°, and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by N-H⋯N and C-H⋯N hydrogen bonds, forming chains propagating along the a-...
متن کامل(E)-N′-(3-Bromo-5-chloro-2-hydroxybenzylidene)nicotinohydrazide
There are two independent mol-ecules in the asymmetric unit of the title compound, C(13)H(9)BrClN(3)O(2), in which the dihedral angles between the benzene and pyridine rings are 8.23 (9)° and 52.84 (12)°. Both the mol-ecules exist in an E configuration with respect to the C=N double bond. The two mol-ecules in the asymmetric unit are linked via weak C-H⋯O hydrogen bonds. In both the mol-ecules,...
