Both 2-chloro- and 2-fluoro<3,5,7-(2)H3>tropone were found to react with lithium diphenylphosphide in teterahydrofuran to give 2-diphenylphosphino<4,6-(2)H2> tropone in what constitutes the first example of telesubstitution by an anionic nucleophile in a non-protic solvent on tropones carrying nucleofugal groups; lithium diphenylphosphide oxide showed the same behaviour.
