Reactivity trends in the base hydrolysis of 6-nitro-2H-chromen-2-one and 6-nitro-2H-chromen-2-one-3-carboxyic acid in binary mixtures of water with methanol and acetone at different temperatures
Kinetics of the base hydrolysis of 6nitro2Hchromen2one (NC) and 6nitro2Hchromen2 one3carboxylic acid (NCC) in water–methanol and water–acetone mixtures was studied at temperature range from 283 to 313 K. The activation parameters of the reactions were evaluated and discussed. The change in the activation barrier of the investigated compounds from water to water–methanol and water– acetone mixtures were estimated from the ... إقراء المزيد

Kinetics of Alkaline Hydrolysis and DNA Interaction of Iron Complexes
Air and moisture stable coordination compounds of some first transition metals such as Cr (III), VO (II), Ni(II) and Mn(II) with newly designed tri- and tetra-dentate imine ligands (HNAP, HNPN and ESPN) were synthesized. Tridentate imine ligands (HNAP, ESAP) were synthesized by reacting 2-hydroxynapthaldehyde (HN) with 2-aminophenol (AP), whereas tetra-dentate imine ligands (HNPN and ESPN) were prepared by reacting 2-hydroxy-1-napthaldehyde ... إقراء المزيد
