The title compounds condense in chloroform to yield tetrafluorobenzo [b]-l, 3, 5, 7- tetraazatetracyclo-[7.3. 13~ 7.1 s~ 9.01~ 9] tetradecan-10-one (l), a reaction proposed to involve both an ortho fluorine elimination and two Stevens type rearrangements. Structural assignment of the fluorescent product was based upon'H, 13C, 19F, and 15N NMR spectra and a complete X-ray crystallographic determination. Additional studies supported the ...
