摘要：

The synthesis of a range of N alkyl 1,4-dihydro-1,4-iminonaphthalenes (7-azabenzonorbornadienes) and reduced derivatives is described together with 1,4-dihydro-1,4- and 9,10-dihydro-9,10- iminoanthracenes. VT NMR studies lead to unambiguous assignment of invertomer preferences; changes in the invertomer ratios and nitrogen inversion barriers are investigated as the electronic and steric environment is modified by variation of substituents in the carbon skeleton and at nitrogen.
