✦ Synopsis


The 'H and 13C NMR spectra of 1,4-diazaphenanthrene (benzo[f]quinoxaline) (1) and some of its derivatives have been fully assigned and most of the coupling constants have been measured. The compounds examined bear a piperidino or methoxy group at the 2or 3-position, or a chlorine atom at the 2-, 3-or 9-position. The spectra of the N-1-oxides of 1 and of 1,4,5,Wetraazaphenanthrene are also given. The syntheses are described.
