The 2-vinylfluorene prepared in Example I is dissolved in 800 milliliters of pyridine and cooled to 0° C. One-half milliliter of a 40% solution of benzyltrimethyl ammonium hydroxide in pyridine is slowly added with air being bubbled through the reaction solution. The initially formed red coloration fades over a period of 1 to 2 hours and the solution is poured into water and extracted with benzene to yield 9 grams (90% theory) of a yellow solid. The residue is chromatographed on alumina (Woehlm basic) and eluted with benzene. Recrystallization from hexane gives 2-vinylfluorenone as a pale yellow material (melting point 69°-70° C). The structure of the product is confirmed by nuclear magnetic resonance and elemental analysis.
