摘要：

The rates of deuteration of pinacolone in pure deuterium oxide at 225 degrees C and 370 psia of (autogenic) pressure were studied. No novel pathways appear to operate in this D2O-catalyzed process under these conditions. Pseudo-first-order kinetics suggest that the reaction -proceeds via classical enolization with an observed first-order rate constant of 8.8 x 10(-3) min(-1), determined at three concentrations.
