The bisdienophilic (hemiporphyrazinato)nickel complexes 1a-d bearing various alkoxy groups were synthesized from diiminoisoindoles 9a-d, diaminopyridines 10a, d, and nickel acetate. Reaction of 1a-d with an excess of pentaene 3 delivered the macrocyclic bisdienes 2a-d. The hemiporphyrezines were characterized by 1H- and 13C-NMR spectroscopy. The NMR spectra of the 1,6,16,21-tetrabutoxy-substituted
由二亚氨基异吲哚9a-d,二氨基吡啶10a,d和乙酸镍合成了带有各种烷氧基的双双亲(半卟啉)镍配合物1a-d。1a-d与过量的戊烯3的反应产生了大环双二烯2a-d。半卟啉的特征在于1 H-和13 C-NMR光谱。关于顺式/反式异构体的存在,讨论了1,6,16,21-四丁氧基取代的化合物1b和2b的NMR光谱。
