The Crystallographic, Spectroscopic and Theoretical Studies on (E)-2-[((4-fluorophenyl)imino)methyl]-4-nitrophenol and (E)-2-[((3-fluorophenyl)imino)methyl]-4-nitrophenol Compounds
In this study, two new salicylideneaniline derivative compounds which are an isomer of each other have been synthesized and characterized by X-Ray Diffraction (XRD) technique, IR spectroscopy, and theoretical method. While (E)-4-(dihydroxyamino)-2-(((4-fluorophenyl)imino) methyl)phenol (1), crystalizes triclinic P-1 space group, (E)-4-(dihydroxyamino)-2-(((3-fluorophenyl)im...
متن کاملSynthesis, Radioiodination and Biodistribution Evaluation of 5-(2-amimo-4-styryl pyrimidine-4-yl)-4-methoxybenzofuran-6-ol
This study describes the organic synthesis of 5-(2-amimo-4-styryl pyrimidine-4-yl)-4-methoxy benzofuran-6-ol (SPBF) as an example of a benzofuran derivative used as a new series of amyloid imaging agents. These benzofuran derivatives may be useful amyloid imaging agents for detecting B-amyloid plagues in the brain of Alzheimer’s disease. The precursor is 1-[6-hydroxy-4-methoxybenzofuran-5-yl]-p...
متن کامل1-[(4-Bromophenyl)(morpholin-4-yl)methyl]naphthalen-2-ol
The title compound, C(21)H(20)BrNO(2), was obtained from a condensation reaction of 4-bromo-benzaldehyde, 2-naphthol and morpholine. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond, closing a six-membered ring. The dihedral angle between the naphthalene ring system and the benzene ring is 76.72 (8)°. In addition to the intra-molecular hydrogen bond, the O-H g...
متن کاملcis-2-(4-Methoxyphenyl)-4-methyl-1,2-dihydronaphthalen-1-ol
The stereochemistry and regiochemistry of the title compound, C18H18O2, were determined by the X-ray analysis. There are two independent mol-ecules in the asymmetric unit in which the dihedral angles between the benzene rings are 88.31 (4) and 86.27 (4)°. The cyclo-hexene rings are in half-chair conformations. In the crystal, O-H⋯O hydrogen bonds link alternating types of mol-ecules into chains...
متن کامل4-(4-Methoxyphenyl)-2-methylbut-3-yn-2-ol
The mol-ecular structure of the title compound, C(12)H(14)O(2), features a nearly coplanar arrangement including the aromatic ring, the C C-C group and the ether O atom. The maximum deviation from the least-squares plane of these ten atoms is 0.0787 (8) Å for the ether O atom. In the crystal, mol-ecules are connected via O-H⋯O hydrogen bonds (involving the hy-droxy O atom both as hydrogen-bond ...
