Reactions of 5-methylphenanthridinium iodide (I) with oxygen, nitrogen, and carbon nucleophiles, respectively, were studied. 5-Methylphenanthridinium iodide (I) yielded in the basic aqueous medium 5-methyl-6-phenanthridone (II) and 5,6-dihydro-5-methylphenanthridine (III). By NMR spectroscopy in the D2O-CD3CN solution 5,6-dihydro-6-deuteroxy-5-methylphenanthridine (IVb) (pseudobase) was observed as an immediate unstable product. 5-Methylphenanthridinium iodide (I) gave the corresponding adducts with methoxide and ethoxide anions, morpholine, piperidine, pyrrolidine, cyanide anion and acetone. Their structure was determined by IR, 1H and 13C NMR spectroscopy. Reactions of 5,6-dihydro-5-methyl-6-morpholinophenanthridine (VII) were followed by NMR spectroscopy. Morpholino adduct VII gave in the CD3CN-D2O solution pseudobase (IVb) and its products of disproportionation: oxophenanthridine II and dihydrophenanthridine III. Treatment of 5,6-dihydro-5-methyl-6-morpholinophenanthridine (VII) with H2O/D2O in (CH3)2CO/(CD3)2CO led to CH3COCH2-/CD3COCD2- adduct XIa/XIb formation, respectively.
研究了5-甲基菲啶铵碘(I)分别与氧、氮和碳亲核试剂发生的反应。在碱性水介质中,5-甲基菲啶铵碘(I)生成5-甲基-6-菲啶酮(II)和5,6-二氢-5-甲基菲啶(III)。通过D2O-CD3CN溶液的核磁共振光谱,观察到5,6-二氢-6-假基-5-甲基菲啶(IVb)(假碱)作为一种立即不稳定的产物。5-甲基菲啶铵碘(I)与甲氧基和乙氧基阴离子、吗啉、哌啶、吡咯烷、氰离子和丙酮反应生成相应的加合物。它们的结构由红外光谱、1H和13C核磁共振光谱确定。通过核磁共振光谱跟踪了5,6-二氢-5-甲基-6-吗啉基菲啶(VII)的反应。吗啉加合物VII在CD3CN-D2O溶液中生成假碱(IVb)和其不均化的产物:酮菲啶II和二氢菲啶III。将5,6-二氢-5-甲基-6-吗啉基菲啶(VII)与H2O / D2O在(CH3)2CO /(CD3)2CO中处理,分别形成CH3COCH2- / CD3COCD2-加合物XIa / XIb。
