3-[(2-Hydroxyethyl)iminomethyl]-1,1′-bi-2-naphthol
In the title compound, C(23)H(19)NO(3), there is an intra-molecular O-H⋯N hydrogen bond, which forms a six-membered ring, and inter-molecular O-H⋯O hydrogen bonds stabilize the crystal structure.
متن کامل1-[(E)-(2-Methyl-3-nitrophenyl)iminomethyl]-2-naphthol
The title Schiff base compound, C(18)H(14)N(2)O(3), has an inter-mediate state between NH and OH tautomers. The mol-ecular structure is stabilized by an O-H⋯N hydrogen bond. The dihedral angle between the naphthalene ring system and the benzene ring is 37.44 (5)°.
متن کاملPolymer/HIO4 : An efficient catalyst for solvent-free synthesis of 2-naphthol azo dyes
A convenient, one-pot method for the synthesis of diazonium salt has been developed by the sequential diazotization of aromatic amines with NaNO2, polymer- supported periodic acid (PPIA) and 2-naphthole under solvent-free conditions at room temperature. By using this method, several types of aromatic amine, containing electron-withdrawing and electron-donating groups, were rapidly converted to ...
متن کامل2-(1,3-Benzothiazol-2-yliminomethyl)-2-naphthol
In the title mol-ecule, C(18)H(12)N(2)OS, the dihedral angle between the two fused-ring systems is 7.2 (1)°. The hydr-oxy group forms an intra-molecular hydrogen bond with the imino group.
