Transfer chemical potentials, solubility and reactivity of 6-Nitro-2H-chromen-2-one and 6-Nitro-2H-chromen-2one-3-carboxylate anion
Kinetic results, rate laws and reaction mechanisms were established for the base hydrolysis of 6-nitrocoumarin (NC), 6-nitrocoumarin-3-carboxylic acid (NCC), in aqueous solution, water-methanol and water-acetone mixtures. The kinetics of the base hydrolysis followed a rate law with kobs= k2[OH-] for all coumarin derivatives under study except 6-nitrocoumarin-3-carboxylic acid (NCC) which followed a rate law with kobs= k1+ k2[OH-]. The kinetic ... Read more
