elemental analysis, and in the case of compounds 1C, 1B+I–, 1C+I–, 1E+I–, 1F+I–, and 1BH–1EH, their molecular structures have been determined using single crystal X-ray analysis and compared to those of related 1H-perimidine derived species. The crystal packings from the solid-state structures of 1C, 1C+I–, and 1CH were compared and revealed further stability of the molecule IC through intermolecular
近萘并稠合嘧啶衍生物,称为 1H-perimidines 或 1H-苯并[ d,e ]喹唑啉,最近已被研究用于多种应用。通过 1,8-二氨基萘与适当的醛的缩合反应合成了一系列 2-取代-1H-perimidine 化合物 (1A–1F)。2-取代-1H-哌啶鎓碘化物盐(1A + I – –1F + I – ) 是通过在弱碱K 2 CO 3存在下使用甲基碘将1H-哌啶鎓甲基化获得的。使用NaBH 4在甲醇中还原perimidine 盐,得到2-取代-2,3-二氢-1H-perimidine 化合物(1AH–1FH)。通过1 H、13 C-NMR 和 UV-Vis 吸收光谱、元素分析对化合物进行了表征,对于化合物 1C、1B + I –、1C + I –、1E + I –、1F + I –,和 1BH–1EH,它们的分子结构已使用单晶 X 射线分析确定,并与相关 1H-perimidine 衍
