23 were obtained crystalline; in solution the latter equilibrates with the hexahydrotetrazine 24 as its dimer. The N-phenylimide 19 is not stable; an isolated solid appears to be a tetramer. Generated by deprotonation of 11−13, the N-arylimides 19−21 undergo in situ cycloadditions to carbon disulfide, phenyl isocyanate, phenyl isothiocyanate, and diphenylketene. The storable CS2 adduct 29 offers a neutral
红色异喹啉鎓 N-芳基酰亚胺 19-23 是偶氮甲亚胺,其 C=N 键是芳环的一部分。得到N-(4-硝基苯基)酰亚胺22和N-(2-吡啶基)酰亚胺23结晶;在溶液中,后者与作为其二聚体的六氢四嗪 24 平衡。N-苯基酰亚胺19不稳定;分离的固体似乎是四聚体。通过 11-13 的去质子化生成,N-芳基酰亚胺 19-21 发生原位环加成反应生成二硫化碳、异氰酸苯酯、异硫氰酸苯酯和二苯乙烯酮。可储存的CS2加合物29提供了N-苯基酰亚胺19的中性来源,因为在溶液中建立了环回复平衡。
