Its first step sees the in situ production of an ester after a carbanion is transformed into an alcohol.
One version of this reaction has a final step that can be carried out using caesium carbonate at 70 degrees or NaHDMS at negative 70 degrees. Like the Reformatsky reaction, Samarium-2-Iodide can be used in this reaction, specifically in place of sodium amalgam in the second step, which sees the radical elimination to give the desired product. Using a heteroaryl compound in this reaction forces a Smiles rearrangement followed by spontaneous elimination, while a one-pot version of this reaction uses a tetrazole reagent and is named for Kocienski.  Its first step sees the in situ production of an ester after a carbanion is transformed into an alcohol. Usually resulting in the E-isomer and using n-butyllithium and a ketone, for 10 points, name this reaction which transforms phenyl sulfones to alkenes.
One version of this reaction has a final step that can be carried out using caesium carbonate at 70 degrees or NaHDMS at negative 70 degrees.
