The kinetic data on the deprotonation of 2-nitroethanol and 2-nitro-1,3-propanediol which concerned the rate of reversible carbon deprotonation by hydroxide ion, water, aminews, and carboxylate ions and pKa values for the ionization at carbon, pK(super CH)(sub a), and oxygen, pK(super OH)(sub a) and ionization of the aci-forms pK(super NOH)(sub a) at 25 degree celsius is reported. The rate constants in the order nitromethane > metroethane > 2-nitropropane is also reported. The rate of proton transfer induced by the substitution of one hydrogen in CH3NO2 by a CH2OH group is also discussed.

The kinetics of aminolysis of a Fischer metal carbene complex, (methoxy(phenyl)carbene)pentacarbonylchromium(O) in a polar solvent is examined. The transition metal carbene complex composed of five alipathic amines is measured in 20% acetonitrile and 80% water at 25 degrees centigrade. Results indicate a general base catalysis since the second order constants increased as amine and hydroxide ion concentrations increased. The mechanisms involved in the process of aminolysis are discussed.
