supporting information; experimental part, p. 1916 - 1919 (2011/05/14)
The first example of the FBW rearrangement using of lanthanum metal and a catalytic amount of iodine was disclosed. When gem-diiodo- and gem-dibromoalkenes were treated with lanthanum metal in the presence of a catalytic amount of iodine, the reductive dehalogenation of these compounds smoothly proceeded to produce the corresponding alkynes in moderate to good yields.

A new simple and efficient transformation of various aromatic ketones to the corresponding halo (dihalo) alkenes is described. The reaction proceeds under mild conditions to give the target products in good yields.
