Strong, non-charged bases are useful in base-catalyzed reactions. Many non-charged nitrogen bases are commonly used in various reactions. Perhaps the strongest non-charged base is shown below. Draw the conj acid of this base and use its structure to explain why it is so basic (resonance forms may help). The pKa of the conj acid is about 26. What is the pKb of the free base?
