Carbonyl Mechanisms: Elimination (1,2-Elimination)

Carbonyl Mechanisms: Elimination (1,2-Elimination)

If the  [1,2] addition is the most important mechanism for carbonyls, then the #2 most important reaction has got to be [1,2]-elimination. This step is just the [1,2]-addition in reverse, except you're expelling a leaving group from a tetrahedral carbon to give you back a new π bond (i.e. a carbonyl).
