✦ Synopsis

We wish to disclose our preliminary studies concerning a new example of relatively slow nitrogen inversion.

At room temperature (22') the 60 MHz nmr spectra of 7-methyl-7-azatetrafluorobenzonorbornadienel (I) and 7-methyl-7-azatetrachlorobenzonorbornadiene2

(II) show the expected proton absorptions: the sharp g-methyl singlet and the methine and vinyl multiplets. These parameters are summarized in Table I.
