2-hydroxy-1-naphthaldehyde 2-methylthiosemicarbazone.
Ligands of the aroylhydrazone class have shown much promise as potential chelators for treatment of iron overload disease and perhaps cancer (Johnson et al., 1982; Baker et al., 1992; Richardson et al., 1995; Richardson & Milnes, 1997). Our previous investigations have demonstrated that 2-hydroxy-1naphthaldehyde isonicotinoyl hydrazone, (II), and several other aroylhydrazone chelators possess a...
متن کاملTautomerism in Schiff bases. The cases of 2-hydroxy-1-naphthaldehyde and 1-hydroxy-2-naphthaldehyde investigated in solution and the solid state.
Schiff bases derived from hydroxyl naphthaldehydes and o-substituted anilines have been prepared and their tautomerism assessed by spectroscopic, crystallographic, and computational methods. Tautomeric equilibria have also been studied and reveal in most cases a slight preference of imine tautomers in solution; a fact supported by DFT calculations in the gas phase as well as incorporating solve...
متن کامل2-Benzyloxy-1-naphthaldehyde
In the title compound, C(18)H(14)O(2), the dihedral angle between the phenyl and naphthyl ring systems is 21.8 (3)°. The packing of mol-ecules in the crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
متن کاملSpectrophotometric determination of nickel(II) with 2-hydroxy-3-methoxy- benzaldehyde thiosemicarbazone
2-Hydroxy-3-methoxy benzaldehyde thiosemicarbazone has been synthesized, characterized and its analytical application investigated. It reacts with nickel(II) in aqueous solution at pH 4.0-8.0 and at room temperature to form a yellow coloured ML (1:1) complex with absorption maximum at 410 nm and molar absorptivity 2.05×10 l mol cm. Beer’s law is obeyed in the range of 0.058-2.347 μg ml of Ni(II...
متن کاملA DFT-based comparative study on the excited states intramolecular proton transfer in 1-hydroxy-2-naphthaldehyde and 2-hydroxy-3-naphthaldehyde
Potential energy (PE) curves for the intramolecular proton transfer in the ground (GSIPT) and excited (ESIPT) states of 1-hydroxy-2naphthaldehyde (1H2NA) and 2-hydroxy-3-naphthaldehyde (2H3NA) were studied using DFT/B3LYP(6-31G) and TD-DFT/ B3LYP(6-31G) level of theory, respectively. Our calculations suggest the non-viability of ground state intramolecular proton transfer for both the compounds...
