Quaternary Ammonium Cations as leaving groups
« on: July 19, 2008, 08:58:41 AM »
Hi!

Why do we create Quaternary Ammonium Cation in Mannich Reactions? -Because they are good leaving groups but:

Why are they good leaving groups? Can someone explain this to me please?

Thank you very much!

If really all you're looking for is theory, then Google and the following pages should provide plenty of information for this and your other questions.
