2018-11-28 16:21:43 Keywords hydroxide ion attack, ONO donors, Kinetics,
Kinetic study of the hydroxide ion attack on and DNA interaction with high spin iron(II) Schiff base amino acid chelates baering ONO donors
Kinetic study of some novel high spin Fe(II) complexes of Schiff base ligands derived from 5- bromsalicyaldehyde and amino acids with the OH– ion and DNA has been carried out. Based on the kinetic data, the rate law and a plausible mechanism were proposed. Kinetic data of the base catalyzed hydrolysis imply pseudo first-order double stage process due to the ... Read more

Kinetic study and reactivity trends of hydroxide ion attack on some chromen-2-one laser dyes in binary water–methanol and water–acetone mixtures
We have investigated the kinetics of hydroxide ion attack at iron(II) chelates with 5-bromosalicylidene derivatives of amino acids (alanine, phenylalanine, aspartic acid, histidine, and arginine) in binary aqueous mixed solvents at 298 K. The observed reactivity trends are discussed in connection with the complexes hydrophobicity/hydrophilicity, transfer chemical potentials of hydroxide ion and the complex, and the solvent effects.
