In a recent column, I mentioned that my graduate research involved the identification and reactivity of novel ketenes. One of my first tasks was to confirm a synthetic pathway for naphthyl-ketene that had been previously developed by a post-doc student and subsequently characterize the product after reaction of the ketene with a free radical.
