Silicon-Nitrogen Bonds. XXXIX. Kinetic Studies on the Spontaneous Hydrolysis, Alcoholysis, and Phenolysis of SilylaminesIt could be shown by polarimetric and DC-metric methods that hydrolysis, alcoholysis, and phenolysis of silylamines are of second order and lead to equilibria.The rate of equilibrium establishment is determined by the position of a preceding protonation equilibrium and by steric effects. The position of the equilibria depends on inductive and steric effects. The enthalpy of activation for the ethanolysis of Me3SiNHPh was determined to 27,2 kJ/mol and the entropy of activation to -231 J/K · mol. The mechanism of the reactions is given.
