摘要

The reaction of p-fluorophenylmagnesium iodide with 6-oxo-2-methyl-4, 5-benz-1, 3- oxazine(from acetic anhydride and anthranilic acid) gave 2-(4'-fluorobenzoyl) acetanilide, which was hydrolyzed to the amine. A Pschorr reaction on the latter afforded 3- fluorofluorenoneJ which in turn was readily reduced to 3-fluorofluorene. The intermediate aminofluorobenzophenone was also prepared by a Hofmann reaction on the ...
