The 1H and 13C NMR spectra of 1,4‐diazaphenanthrene (benzol 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 2‐ or 3‐position, or a chlorine atom at the 2‐, 3‐ or 9‐position. The spectra of the N‐1‐oxides of 1 and of 1,4,5,8‐tetraazaphenanthrene are also given
1,4-二氮杂菲(苯并 f 喹喔啉)(1) 及其部分衍生物的 1H 和 13C NMR 谱已完全确定,并且大部分偶联常数已被测量。所检测的化合物在 2 位或 3 位带有哌啶基或甲氧基,或在 2、3 或 9 位带有氯原子。还给出了 1 和 1,4,5,8-四氮杂菲的 N-1-氧化物的光谱。描述了合成。
