Heptafulvene (Chart 2, I), a conjugated, non-benzenoid hydrocarbon of theoretical interest, has been synthesized by a Hofmann elimination on trimethyl 7-cycloheptatrienylmethyl ammonium iodide. Non-isolable, stable only in dilute solution, I is assigned the heptafulvene structure on the basis of catalytic hydrogenation to methylcycloheptane; indication of a methylene group from I. R. and ozonolysis to
通过在三甲基7-环庚三烯基甲基碘化碘上进行霍夫曼消除反应,合成了具有理论意义的共轭非苯甲酸酯类七氟醚(图2,I)。不可分离,仅在稀溶液中稳定,在催化加氢成甲基环庚烷的基础上,我被赋予了七氟甲醚结构;指示从IR和臭氧分解成甲醛的亚甲基; 精细的可见光谱和紫外线光谱与高度共轭的系统相关联;对酸有明显的敏感性;并与乙炔二羧酸酯反应,得到(最终)a唑衍生物。
