WebA comparative study of the concerted hydrolysis of H-, CF 3 -, CH 3 -, and Ph-substituted N -sulfinylamines (R−NSO) and isocyanates (R−NCO) was performed using B3LYP/6-31+G (2d,2p). The “two-water-molecule” model was found to be sufficient for a proper description of the hydrolysis reaction for both classes of compounds. Webisocyanate, the solvent is also concerned as a dielectric continuum, simulating the influence of the bulk. For the sake of comparison with the hydrolysis of isocyanates, which has been reported in the preceding paper,12 a similar approach has been employed. Results and Discussion A. Experimental Aspects.
