| Notes: |
The velocities of four acid-catalysed hydrogen isotope exchange reactions between diazoacetone (1) and water (T → H, T → D, D → H, and H → D) and of three exchange reactions between diazoacetaldehyde (2) and water (T → H, T → D, and H → D) have been measured. The exchange D → H of 1 was found to be submit to general acid catalysis (αB = 0.6). The rates of protonation of primary and secondary diazocarbonyl compounds of similar structure were found to be quite similar, in spite of difference in mecanism (A-2 and A-SE2, respectively).
