Barton, O’Brien, and Sternhell use this article and the protocol described within it in order to demonstrate how they converted the ketone portion (16) of a larger molecule into a vinyl iodide (intermediate between 16 and 18). The article explains how Barton, O’Brien, and Sternhell unintentionally came across, but developed and proved a method to convert ketones and aldehydesinto hydrazones. Then, through oxidation by iodide, vinyl iodides or gem-ni-iodides are formed.
