Chapter 11, Problem 11.46P
Tautomerization in base resembles tautomerization in acid, but deprotonation precedes protonation in the two-step mechanism. (a) Draw a stepwise mechanism for the following tautomeization. (b) Then draw a stepwise mechanism for the reverse reaction, the conversion of the keto form to the enol.
